Self Priming Pumps
Extending the Vertical Seal Less Pump further, a 40mm self-priming version has been introduced for the discharging of chemicals / effluents from ‘blind’ sump tanks and pits.
Designed on the same ‘MJ’ Vertical Seal Less principle the MJ40K SP also allows running dry or against closed valve for indefinite periods.
Self-priming is achieved by a secondary impeller which draws a supply of liquid from a ‘priming pot’ attached to the side of the pump, manufactured from corrosion resistant thermoplastic.
The unit has a nominal capacity of 20m3/Hr at 20m head and a suction lift capability of up to 3.5m.
For either permanent or transportable use the 32/125 self priming pump is a robust unit manufactured in polypropylene and incorporates an inboard general purpose chemical seal.
The unit has a nominal capacity of 1 2m3/Hr at 1 2m head with a suction lift capability of 4m.
