Prime Assisted De-watering Pumps
De-watering pumps are very robust pumps & commonly found on construction sites. The hire pump industry also prefer these units as a heavy duty asset that will generally stand up to untrained operators & misuse.
They are normally combined with a separate priming pump to ensure all gases are removed from the suction leg & can tolerate running dry for short periods if required.
Advantages
Ease of use & setup due to external priming function.
Reasonable heads & flows at good operating efficiencies.
Can tolerate operator misuse & running dry for short periods.
Heavy duty construction & reliable operation.
Can operate on the ‘snore’ where suction levels are reduced to the Hose Inlet.
Limitations
Expensive pumps to maintain & purchase.
Costly spare parts.
