QXN series clean water cast iron high pressure submersible pumps

Product Code : SUB-12

Pump Application:

This range of heavy duty submersible clean water pumps is suitable for both domestic and commercial use.   It is suitable for pumping clear water or dirty water with small minor non abrasive particles.   Fitted with a high pressure impeller for high heads.   Complete with a double Sic-Sic mechanical seal contained in an oil chamber.   Because of the design, the heavy duty ball bearing motor is cooled by the pumped water, therefore this pump can be operated partially immersed.

The pump is to be installed in an upright position for both fixed and portable.   Do not run your pump dry.   To prevent damage, use a rope or chain to position and retrieve your pump – never use the electric cable for this purpose.


Caution 1:

Don’t use this pump for recirculating or filtering pools, spas, etc.   While these pumps are built to a high safety standard, they are not approved for installations where people will be in the water while they are operating.
