Kay and Engelhardt Upright Bass Replacement Volute ...

Kay and Engelhardt bass necks are made in bulk runs and do not feature hand-carved scrolls on their pegboxes. Instead, a wooden "applique" is applied to each side, which simulates a carved scroll. They've pretty much always been done this way, from the beginnings of Kay, up until Engelhardt started making their Kay-styled basses in .

We've been carrying the Engelhardt replacement volutes for many years; they're an exact match for the ones that Engelhardt has been putting on their necks for decades.

Roger Stowers of KayBass.com (an excellent resource for Kay Bass information!) did the painstaking measurements of the old Kay bass volutes some time ago, and has been selling them at his website for years. Having tired of going through the trouble to sell things on his website (which is a resource, not a store) he contacted me in the fall of to see if I'd take over the future manufacture and selling of the volutes. We are very pleased to pick up where he's left off, and sell these volutes directly to you!

These are ALL WOOD scroll pairs; there are three slightly different designs based on what bass you have. If you want the scroll to match up perfectly with the shape of your pegbox, (and be historically correct!) pick the one that is designed for your bass. The three models available are:

• Oval model for Kay basses until model year
• Round model for Kay basses from on
• "Plain" style for Engelhardt basses (all years)

See the graphic for actual photos of each model. Don't know what year your bass is? Check your serial number against our Serial Number List!

Volutes, as these scrolls are called, are sold in pairs only, as the nature and size of the volutes changed over the years, so a single one might not perfectly "match" an existing one from an older neck.

They are designed to be glued to the neck and finished/stained the same as the neck. (See the photo below for an example of the volutes installed on a neck). They are made of boxwood, which is a good stain/color match for a maple neck.

Again - what you are buying is not an entire pegbox, it is the matching pair of "glue-on" scroll pieces shown in the photo above.

BUYING GUIDE FOR WATER PUMPS

Water issues in India have always been troublesome, both in rural and urban areas. Irrespective of the fact that the rainfall was good enough or the lakes that supply water are filled or not, we often face the wrath of water scarcity. In order to strike back, mankind came up with a smart device called "Water Pumps".

With simple mechanism and innovative technology, these water pumps draw water from underground sources and supply it to our homes. In most rural and industrial areas, these water pumps are eradicating the issue of water scarcity and are proven to be an amazing help.

Now, as there are many options available in the market; you might be confused which one to invest in. So here's a simple guide to help you make a wise choice.

WHAT KIND OF PUMPS ARE AVAILABLE IN THE MARKET?
Depending on your needs and necessities there are two major types of pumps available in the market, namely - Domestic and Agricultural Pumps. They are engineered in a way that makes an appliance a perfect pick. Under the broad section of these two kinds of pumps there are several different types available which have their salient features. Read on to have a better understanding of it.

A. Domestic Pumps
As the name suggests, Domestic Pumps are those used in homes for daily water consumption. These pumps have a lower flow rate and less power as compared to the ones used for agricultural purposes, since they have to be pumped into small areas. The various domestic pumps are:

1. Self-Prime Regenerative Pumps
A Regenerative Pump has vanes fitted on either side of the rim that rotate in a ring-like conduit in the pump's casing. The fluid does not discharge from the tip of the impeller but is re-circulated back to the bottom of the impeller. This re-circulation or regeneration is how the pump re-primes itself.

These pumps are suitable for handling clear cold fresh water, free from abrasive particles and chemically aggressive substances. Suitable for domestic water supply, lawn sprinklers, gardens, etc. These pumps due to their self-priming capability can remove air and hence is suitable to suck water from pipelines and, therefore, does not require a foot valve.

2. Centrifugal Pumps
Centrifugal Pumps serve the purpose of circulating water by the conversion of rotational kinetic energy to the hydrodynamic energy of water flow. The rotational energy is derived from an electric motor. The other kind of a centrifugal pump with a similar mechanism is the Jet Centrifugal pump which uses a stream of sucked water for creating a jet to improve the drawing capacity from the underground resources.

These pumps are suitable for handling clear cold fresh water, free from abrasive particles and chemically aggressive substances. Suitable for domestic water supply, lawn sprinklers, gardens, small farms, irrigation, agricultural applications, draining of wells and tanks, filling water in swimming pools, etc. These pumps have higher discharge compared to regenerative pumps. The pump has to be installed with a good quality ISI foot valve. Excellent hydraulic performance and higher operating efficiency compared to regenerative pumps with lower maintenance costs.

3. Submersible Pumps
A Submersible Pump is a device with a sealed motor which is completely submerged in water bodies, especially open wells and bore wells. They are an efficient and wiser choice since they do not require any priming as they are already submerged into water. They are further divided into two types:

Open Well Submersible Pumps ( Water Cooled/Oil Cooled) (For Open-Well Applications)

Tube Well submersible Pumps ( Water Cooled/Oil Cooled) (For Bore well applications)

These pumps are suitable for handling clear cold fresh water, free from abrasive particles and chemically aggressive substances. Tube well submersible pumps are suitable for 3", 3.5" & 4" bore wells.

4. Bore Well Compressor Pumps
Bore Well Compressor Pumps are especially designed for drawing water from deep bore wells with specific diameters. Air pressure is used in this machine to lift the water from deep bores.

These pumps are best suited for comparatively less yield bore wells, having a depth of up to 600 ft. Compressor Pumps can be used in bore wells containing muddy water, where tube well pumps are not suitable. There are two types of compressor pumps, Monobloc and belt driven types. Discharge of the compressor pumps depends on the yield of the bore well.

5. Pressure Booster Pumps
A Pressure booster pump is a quality appliance, which you should go for if you want smooth and pressurized water supply in your home. They are especially engineered to supply you with required pressurized water according to your needs.

The automated pumping system is supplied with a pressure tank for constant water pressure across all openings connected to the piping system making it an ideal choice for use in residential buildings. As the water pressure drops to a set level, the pump automatically starts to pump water and as the consumption drops the pump stops automatically when the outlet pressure rises to pre-set stop pressure.

6. Shallow Well Pumps
Shallow Well Pumps, are a very novel pick for shallow wells. The reason being that they have great suction power and are a good choice for rural areas.

Shallow Well Pumps having suction head of up to 8 meters and hence can be chosen as an alternative if suction head is greater than 6 meters which is the capacity for normal self-prime pumps.

B. Agricultural Pumps
Agricultural pumps are the saving grace in rural areas as water pumps are necessary for good crop production. It is also very important for one to choose the correct pump and to help you make this informed decision, here are the different types of agricultural pumps:

1. Centrifugal Monoblock Pumps
Like regular centrifugal pumps, monoblock pumps too circulate water by the conversion of rotational kinetic energy to the hydrodynamic energy of water flow. However, since they have to cover a larger area, these pumps are more efficient and have a higher flow rate (approx. 25LPS).

2. Submersible Pumps
Submersible Pumps keep the issue from priming away and are a better option in the farming sector. Agricultural Submersible Pumps also work in the same manner but there is a wider range available in this category.

While there are the regular Open Well ones, we also offer options for 4", 6" and 8" bore wells. These pumps comes with a higher power of 60HP, with maximum operable depth of feet and provide a flow rate of up to 38LPS.

What to look for in a water pump?

Vertical Suction

This involves the distance through which water must be sucked out of its source in order to reach the pump. If your pump is mounted at well top, then the distance from water level to the pump position is the vertical suction. This parameter needs to be cross-checked against the pump suction head before purchasing.

Vertical Delivery Head

The vertical distance between the pump and the delivery tank is called the vertical delivery head. This height need to be matched with the pump delivery head to ensure that the selected pump suits your application.

FIVE THINGS TO KNOW BEFORE BUYING A PUMP

As a pump supplier with over 45 years of industry experience, we understand that customers often have questions and uncertainties when it comes to purchasing a pump. In order t o help you make an informed decision, we've broken down the key information you need to know into five categories: fluid, flow, discharge, suction, and options. Our blog will provide you with a set of questions to consider, as well as helpful links to expand your knowledge on these topics.

Fluid

- What you are pumping (water, oil, slurry, etc.)

What is the specific gravity and viscosity of your fluid?

Are chemicals present? What are the names and concentrations?

Are there solids? What is the particle size, percentage of fluid that are solids, & are they smooth or sharp?

What is its temperature? (Ambient is 20°C)

Flow - The rate you want to transfer the fluid at.

Are you decanting, dosing or transferring?

Are chemicals present? What are the names and concentrations?

Discharge &#; The line from pump to discharge point.

What will the vertical and horizontal lengths be?

Have you taken 

friction loss

For more information, please visit double volute casing.

into account? (Pipe type,

viscosity

, etc. affect this)

Are you dosing or transferring into a pressured pipe, if so what is the pressure? Or is it 

open free flow

?

Suction &#; The line from source to pump.

What&#;s the length of the suction line?

?

Will you need a self-priming pump

Are you pumping from a dam/well or is it flooded suction

Options &#; Preferences and accessories.

Identify your preferred power source and check stability (240v, 415v, 50/60 Hz, mining/industrial, diesel, petrol, air, etc.)

Check to see if you&#;ll require base plate, trollies for transportation,variable speed, etc.

Definitions (For more pump terms see our Glossary of Pump Terms)

Base plate: The plate on which the pump and motor are mounted.

Decanting: Gradually pumping from one container into another.

Dosing: A controlled method of pumping in order to discharge exact amount of fluids.

Flooded suction: If the pump is below the liquid source, and the suction is fed by gravity. This is a preferred method for centrifugal pumps.

Fluid: A state of material that continually deforms under an applied shear stress. Gas, liquid and plasma are examples.

Friction loss (pump): Friction between the pump and the process fluid results in loss of pressure. Different parts of the pump are more susceptible to this force than others.

Friction loss (pipe): The force produced as the process fluid flows through the pipes of a system. Caused by movement of the fluid internally as one fluid layer moves against another. Also caused by movement of the fluid against the pipe wall. Rougher pipes will lead to higher friction.

Open free flow: When the discharge pipe or hose is fully open at the end with no restrictions.

Self-priming pump: A pump that contains a reserve amount of process fluid that helps to create an initial vacuum and lift fluid from the source.

Specific Gravity (SG): The ratio of the density of a substance compared to the density of a reference (usually water at 4°C).

Suction line: The suction line of a pump system is piping which transports fluid material from its source to the pump itself.

Transferring: To move a substance, usually a liquid, from one place to another.

Variable speed motor: Can be used to control flow in the system by varying the impeller speed.

Viscosity: Resistance to gradual deformation of a fluid by shear or tensile stress.

Chemical Transfer Pump Buyers Guide

Welcome back to another edition of Inspector Pumphead Recommends! In this column, I will show my skills and experience as an Inspector to highlight and explain the features, specifications and benefits of specific pump models. The pump that is featured here might be a best-seller, be seasonally appropriate or have unique features that set it apart from other pumps of a similar type.

In today&#;s edition of &#;Inspector Pumphead Recommends&#; I will be highlighting the AMT 12SP10C-3P self-priming cast iron chemical pump. AMT is a great brand for pumps used at job sites and they carry many other centrifugal chemical pumps.

What is a Chemical Pump?

A chemical pump is simply a pump that is is able to transport or process chemicals in addition to water and wastewater. This is due to the special construction of the pump which is resistant to corrosion or the other ill effects often caused by chemical substances. Keep in mind that these pumps can&#;t pump any old universal chemical. As with any other pump, they are built to precise specifications and can handle certain applications.

For instance, the AMT 12SP10C-3P is not to be used with petroleum based liquids. But it is still one of the best chemical pumps on the market.

Application

This AMT pump is referred to as a general transfer chemical pump and is specifically designed specifically for commercial and industrial applications. The main applications are high volume liquid transfer, wastewater drainage and chemical processing. This pump can often be found in factories, refineries and chemical processing plants.

The AMT 12SP1C-3P can handle liquids with specific gravities up to 1.3 Specific gravity, telling you the density of the liquid. It is the ratio of the density of substance to the density of the reference substance, which in the case of liquids is water. To put it more simply, the specific gravity measures how dense the desired liquid or chemical is, as compared to water at 4° C.

Specific gravity can vary depending on temperature and pressure so the sample substance and the reference substance should be compared with the same conditions. Some common liquid substances with a specific gravity of 1.3 or less include acetylene, ethanol, crude oil, natural gasoline and sea water. The AMT will handle those liquids and many others. For temperature, it can handle fluids ranging from 40° F to 180° F.

Performance

Here&#;s the performance curve for all AMT self-priming centrifugal pumps:

The 12SP series can reach a maximum capacity of approximately 85 GPM and a maximum head of about 60 ft. TDH.

Construction

Naturally, any chemical pump will feature rugged construction, in this case a cast iron casing with seals made of EPDM (ethylene propylene diene monomer) rubber and EPR (ethylene propylene rubber) seals. The dual volute is built to handle working pressures up to 125 PSI and reduces radial load on the motor. The impeller is self-cleaning and clog resistant and can handle &#;&#; diameter semi-solids. The dual cycle NEMA 56J motors have stainless steel shafts.

A built-in check valve adds to the convenience and allows self-priming up to 20 ft. after the initial prime. A back pullout design also allows for easy service, maintenance and cleaning. This is an impressively designed pump that will be able to move wastewater or chemicals for your application.
