Hot Water Pumps

Applications by Market

hot-water

Pumping hot fluids can be a difficult application. Concerns include avoiding cavitation, and maintain proper lubricity in the hot water pump's hydraulic end.

Hot Water Pumps for Boiler Water

A large refining facility requires continuous recirculation of hot boiler water. The hot water pump application requirements included: direct coupling, explosion proof motor, and only a reservoir tank to offer for supply of near boiling water.

Normally a pressure-feed suction would be necessary to avoid cavitation. By increasing the supply line plumbing to 2", positioning the hot water pump close to the tank, and changing some plumbing at the top of the tank to create a full 10 feet(3.1 m) of static head, the hot water pump was able to run at full RPM without cavitiation.

Vacuum Tank Cleaning Trucks Utilize Hot Water Pumps

An OEM, who manufactures Vacuum Tank Cleaning Trucks are used in the sewage industry for a variety of related applications including cleaning of portable toilets.
A specific requirement was the ability to run the hot water pumps dry. Hydra-Cell hot water pumps have no cups, packings or seals, and therefore, can run dry.

Hydra-Cell® Diaphragm Pump Advantages

The seal-less nature of the Hydra-Cell diaphragm pumps enable charged and dirty liquids to be processed without need for fine filtration to protect the diaphragm pump.

The Hydra-Cell diaphragm pump needs little maintenance and can operate at continuous duty at high pressure.

Pulsation is low, so dampeners may not be required for most Hydra-Cell® diaphragm pumps.

Hydra-Cell® diaphragm pumps can handle solids up to 500 microns, or more. They can be pumped without fine filtration. System costs are reduced and maintenance is simplified.

Most diaphragm pumps in the Hydra-Cell® diaphragm pump range can operate at any pressure from <1 bar up to at least 70 bar. Some models up to 170 bar.

Seal-less design distinguishes the Hydra-Cell® diaphragm pumps from other diaphragm pumps and is the basis of its long service life - many of the liquids pumped are harmful to pump seals. The Hydra-Cell® diaphragm pumps are tolerant of small solids, resistant to chemical and corrosive attack.

Energy savings. Compact and highly efficient (80-85%), a Hydra-Cell® abrasive pumps can be fitted with a smaller motor than would be required by many much bigger hot water pumps for equivalent flows and pressures.
