Established in 1923, Peerless Pump Company of the United States offer large range of centrifugal pump for a variety of application.
AJ Holmes Pump Company are able to offer a complete range of Peerless products, from new pumping applications to spare parts and complete replacement units for existing installations.
The Peerless range is vast ranging from the fantastic Hydroconstant variable speed drive to split case centrifugal pumps to vertical turbine pumps. Peerless manufacture ANSI process pumps.
Peerless pumps are a major manufacturer of fire pumps and fire pump systems, from single pumps to large diesel driven systems.
Hydrocontant Variable Speed Drive
The hydroconstant has been made by Peerless pumps in the USA and UK over the years. It has also been made under liscence by FMC, Powerwise and Varley over the last 30 – 40 years.
A.J Holmes Pump Co. hold the serial number records to all the hydroconstants sold in the UK and Europe over the last 40 years or so. We can identify spare parts and replacement units for any unit still in operation.
Hydroconstants are still used throughout the UK by customers such as the Bank of England, Lloyds of London, United Utilities and many other water authorities. They have a very long and reliable working life often not requiring parts for over 20 years. This makes them a very cost effective and sensible investment compared to other newer technology.
The basic use for a hydroconstant is to maintain a constant water pressure in a system irrespective of the flow demands. This is done by using a fluid coupling to vary the output speed of an attached centrifugal pump creating a flat curve in terms of pressure against flow.
This is of particular use in large building where a particular pressure is required but demand is unknown or variable.
Hydroconstants can also be used to maintain flows and liquid levels, this is of particular use in breweries, dairies and production lines.
The beauty of the hydroconstant is that it can be coupled to any make or type of centrifugal pump which gives it a vast range of applications from clean water to hygienic and industrial processes.
