Making choosing and using pumps
pleasurable!
How should industrial users select the right pump with the confidence of, say, the large water utilities with their access to performance records? By choosing an experienced pump supplier
The operators of industrial plants throughout the world have to cope with a wide variety of fluid transfer and waste treatment processes of which the most common, and troublesome, component is often the pumps The simple fact is that there are a very large number of pump manufacturers, each offering a bewildering array of types and sizes, which almost ensures that the best pump for the job will not make it to the site

Prerostal system succeeds where deep sumps fail
After a problem at the Barry Bathing Waters Improvement Scheme, a solution was found in the form of a system of pumps that automatically match output with inflow, using a system known as Prerostal.
Twelve pump order for Pumping Station
Hidrostal, the fluid management specialists, has recently won an order for twelve pumps for the Ness Point Pumping Station, near Lowestoft in Suffolk.
The replacement of an unsuitable pump is also likely to be less than ideal for the same reasons.
Statistics do not bode well for the occasional industrial purchaser.
The large water utilities, each with tens of thousands of pumps handling municipal wastes, do not face the same difficulties and are able to select the right pump because of their ready access to performance records and fluid technology expertise.
So how should industrial users proceed? So what is being (or can be) pumped? This question is at the heart of a trouble free installation.
The answer has three important components, namely; Will the liquid damage the pump?, Will the pump damage the liquid?, and Are there factors present which lead to breakdowns and shorter service availability? As the range of liquids is vast, the materials from which the parts in contact with the pumped liquid must be equally varied.

The Abu Dhabi Sewerage Projects Committee chose Hidrostal's prerotation pumping system, as it offered several advantages over conventional centrifugal pumping installations.
Experienced pump suppliers must be able to supply casings, impellers, bearings and other parts in materials suitable for dealing with the most abrasive and aggressive liquids.
Leading pump manufacturer Hidrostal is one such company.
From a core business viewpoint the most ignored feature of pump selection is the damage to the pumped liquid.
The high turbulence within pumps, and in the downstream tail effect within the pipe, can impart significant damage to molecular structures.
Fluids as diverse as paints, yoghurts and bio-cultures such as activated sludge, all require the gentlest handling.
Physical damage is equally important.
The undamaged transfer of fruit and vegetables is a frequent duty as is the transfer of live fish.
High speed, centrifugal pumps are not well suited for such damage free situations, even when using the famous non-clog variants which pass a 75mm sphere.
All of the damage free applications mentioned, along with many others, have been successfully undertaken by Hidrostal.
The unique design of pump manufacturer Hidrostal's screw centrifugal impeller is able to deal well with all fluids, including those containing long fibrous materials, the cause of so much downtime from blockages and bearing failures.
Hidrostal pumps are suitable for applications previously needing a positive displacement pump, particularly those viscous materials and liquids with high solids concentrations.
Hidrostal are a market leader in the gentle, trouble free, transfer of all difficult and sensitive fluids.
So how much do you need to pump, now and next year? With damage issues sorted the actual sizing of the pump usually occupies little time as the end user is expected to supply the figure.
No matter whether it is litres/second, gallons/minute, or even tons (or tonnes) per day, all absolve the pump supplier, and that is that.
Not too sure of the flow, now or in the future, then what is needed is an expensive variable speed unit.
However, help is at hand.
Innovative transfer specialist Hidrostal, is now able to deliver a pump output, which matches inflow, whilst using a fixed speed motor.
Hidrostal's Prerostal technology provides a variable output without the need for a variable speed drive.
The flow to each pump enters a compact sump and the basin geometry produces a rotational speed which is proportional to inflow.
The output of the fixed speed pump is directly related to rotational speed and, consequently, output matches inflow.
Pumping for Pleasure? Yes is the simple answer.
No pump downtime means uninterrupted production.
The breakdown of a manufacturing process pump, or pumps within the plant treating production waste, is not just a pain for the maintenance department.
Production can cease.
This is every manager's nightmare, particularly where continuous processes are involved.
Real costs pile up and the situation is often compounded when it is found that no spares are available for that immobile pump.
Pleasure it most definitely is not.
Production pleasure is influencing the initial selection and never experiencing problems thereafter.
This is possible, as major multi-national companies are well aware.
With trouble free installations world-wide, international pumping specialist Hidrostal have a great deal of experience in the problems faced by industrialists.
To deliver the maximum possible benefits Hidrostal provide a full design, installation and commissioning service.
The pumped liquid is assessed by experts, the correct pump materials are used, and the Hidrostal pump design ensures that the best possible efficiency is delivered and most importantly is sustainable.
Hidrostal's pumps are the true gentle giants of liquid transfer.
