Simplicity, versatility and reliability have been the hallmark of the LPA® brand of pumps for over 25 years. Versatility is emphasised by the wide range of uses. Simplicity is highlighted by the ” orbital” magnetic drive, leak proof design. Reliability is proven by a combined operating record of over 315 million hours in a full time refrigeration environment.

Our latest range of self unloading CO2 LPA® pumps inherit the exceptional reliability of the LPA® range and covers a wide range of operating conditions from 1 to 65 GPM (3.78 to 245 litres/min), design working pressures of 1087 psi (75 bar) as standard and capable of providing up to 83 feet (25 metres) of head to suit most industrial applications.

A well know Distribution center in Holland has recently installed Model 875 seen above to substantially improve their refrigeration performance. The plants compressor rack is located 18 feet (6 meters) below the expansion valves which is providing a 35 to 40% improvement in energy savings overcoming the liquid line pressure drop by using the LPA® pump.

How is my power being wasted?

Present day designs with head pressure controls were developed some 65 years ago. Higher head pressures were designed into a system so it would function well at lower outdoor temperatures. These higher pressures were needed to deliver the refrigerant to the cooling coils. Power costs a half a century ago were not a factor so the added cost of operation with lower efficiency did not matter.

At today’s power costs, inefficiency is an unacceptable part of your overhead. See Brochure: Improving-Refrigeration-Dynamics-LPA

Energy Efficient LPA® Pumps..

for Supermarkets, Process Cooling, Cold / Frozen Storage, Blast Freezing, Data Centres and much more!

HY-SAVE® manufactures a range of LPA® pumps that saves energy in refrigeration or air conditioning applications. Depending on your geographical location, energy savings can be in the region of 12 to 48% annually. Recently launched,  our new range of high efficiency Co2 LPA® pumps designed specifically for Co2 refrigeration applications  to further improve efficiencies.
