Industrial Pump Division

Crest Process Engineering, Self Priming Centrifugal Pumps for a wide range of industries and applications.

Crest Process Engineering are able to supply, install, maintain and repair the 'J' Series industrial pumps.

High and dry with J self‑priming centrifugal pumps

J pumps are self‑priming centrifugal pumps with open impeller handling large diameter solids and replaceable wear plates. They have easily opened inspection covers and externally lubricated mechanical seals.

Simple construction. Only one moving part: the impeller

Easy inspection of impeller

Quick self‑priming without foot valves. The pump self‑primes automatically to heights of up to 7½m

Large diameter solids handled

High resistance to abrasive liquids. The wear plate is easily replaced and can be covered with an abrasion and oil resistant rubber facing.

Externally lubricated mechanical seal. Lubrication prevents damage during dry running and stops leaks or air or liquid along the shaft.

Easy to install. Only the suction hose is immersed in the liquid. The pump can be set up high and dry in the most convenient position for inspection and maintenance.

Long life. The parts subject to wear can be easily replaced one or more times to restore the original performance.

Applications

J pumps are used when one or more of the following are required: self-priming, solids handling, resistance to abrasion. J pumps can handle liquids up to a viscosity of about 50 mm²/s (cSt)

Industry: Transfer of clean or dirty neutral, acid or alkali liquids; liquids containing sand, mud or solids in suspension; clean or dirty low viscosity petroleum products or solvents; milk of lime, caustic soda; washing, cooling, circulation; smoke scrubbing; emergency duty.

Civil engineering: Flood drainage; sewage pumping; fire fighting; recovery of dangerous liquids.

Naval duty: Loading and unloading; bilge pumping; washing, fire fighting, stripping, sanitary duty and circulation.

Waste treatment: Pumping polluted, hot or corrosive waste water containing sand, mud or solids in suspension; dosing neutralising liquids; pumping out settled sludge.

Construction industry: Dewatering excavations, canals or ponds; ground water dewatering with wellpoint systems or drains; water supply from wells or canals; hosing down concrete castings.
