• Building Services
• Sumps and Basements
• Mining
• Civil Construction
• Industry
• Municipal
• Processing

Technical Data: 

 

Type	Centrifugal	Submersible
Medium	Sewage	Waste water	Rain water	Living water
Flowrate	Min.:10m3/h	Max.:6000m3/h
Head	Min.:7m	Max.:62m

Features:

• High strength cast iron pump construction.

• Impeller options are available to suit a range of applications and pumped products including single,      double or triple vane.

• 420 Stainless steel shaft.

• Built in cooling system allows operation when motor is submerged or above water level.

• Optional external cooling available.

• Cast iron replaceable neck ring insert.

• Class F motor insulation with maximum working temperature of up to 155°C.

• IPX8 motor protection.

• Dual mechanical seals with carbide/tungsten seal faces on pump side and graphite/silicon carbide faces  on motor side provide effective sealing between motor and wet end.

• Mechanical seals are oil bath lubricated.

• Motor stator incorporates three shutdown temperature control sensors which automatically detects motor temperatures at 125°C.

• Oil chamber incorporates a water leakage probe which detects when water-to-oil ratio is too high and cuts off power to prevent motor damage due to oil contamination.

• Motor incorporates water detection sensor at the top and a float switch in the bottom to detect the ingress of water and cut power to prevent motor damage.

• Available with a wide range of protective coatings and paint options.

• Optional product grinders available on request.
