About Our Pumps

KPM Pump technology has been developed to reduce ownership cost and exceed SOLAS requirements. KPM's unique pump features are a result of 5 years' research and development and partnership with their customers.

Re-useable Gaskets:
All seals are Viton Rubber and will give high performance sealing over extended periods of time.
Reduced Damage from Solids:
Run Dry Porting Technology TM (RDPT) allows run dry capability with optimum flow and no damage by sand or solids.
High Quality Seals
All seals are double lip and fully encapsulated to stop corrosion. Most applications have two double lip seals.
Stainless Bearings
All bearings are over specified stainless steel /rubber sealed for protection and long service life at sea. Double and rear bearings are configured in heavy duty applications.
Lightweight and
Corrosion Resistant

All KPM Endurance Pumps TM are machined from solid billet T6 aluminium and coated with 50 microns of hard anodising with silicon surface impregnation. Since the coating is a dielectric no current can flow to give galvanic reaction.
Run Dry Exceeds SOLAS
All KPM pumps will run dry with standard Neoprene and Nitrile impellers. No removal tools required to replace the impeller.

Replaceable Liner
Internal Cam sleeve can be replaced when worn. made from bronze or Hard coat alloy. Competitors liners are plastic.

Reduced Endplate Wear
TIBS TM impeller seal faces reduce friction , increase long term sealing and cut horse power consumption by 70%. These seals also wipe the shaft and stop grit reaching the seals.


  Run dry capability Exceeds SOLAS: Tested at 700RPM and 1200RPM dry for 5mins dry and 5 mins wet before prime is lost. The run dry capability has been tested by independent customers who’s results have duplicated KPM's. Tests of up to 20 min run dry have been undertaken by military customers with no damage to the impeller, but slight loss in prime height.
  Cost to customer (Over 5 year period): Actual costs of port authority customer replacing pump every year and replacing impellers and wear plates until pump body needs replacement. Like for like basis not including extended wear capabilities of KPM Pump. The comparison does not include the labour cost or down time.
  Pumps in abrasive waters tend to wear on one side and causes loss of prime and performance. The KPM pump chamber can be rotated which will prolong the pump life by 75% above competitors offerings. When the liner or end plates have worn they can be simply replaced without buying a whole pump chamber which is costly and difficult to obtain.
  Customers have reported increased run time between rebuilds or impeller replacements from 300 hours (existing) to 1500 hours (KPM replacement) in waters containing high levels of sand. Several customers have reported using the same impeller for durations of 4 years. This results in reduced downtime and labour cost.

Flow Rates
All flexible impeller pumps loose flow as the head pressure increases due to deflection of the rubber impeller. KPM pumps are designed to give optimum flow at 3500 rpm with a pressure of around 14.5–17.5 PSI, in order to give greatest cooling whilst going onto the plane at which point engine torque is the highest. At 18 PSI natural force flow is allowed by KPM By Pass porting technology at which point the pump is not delivering the main flow, but from the natural flow created from the forward motion of the vessel. As a result pump horse power and wear reduces significantly.
