General Information
The Depon WQ Series SubmersibleSewage Pumps are electro submersible centrifugal pumps designed for pumping waste water, effluent and solids laden water in municipal, industrial, mining and civil construction applications.
Applications
Transfer of waste water, effluent and solids
laden water for:
• Water Treatment
• Building Services
• Sumps and Basements
• Mining
• Civil Construction
• Industry
• Municipal
• Processing

Type | Centrifugal | Submersible | Â | Â |
Medium | Sewage | Waste water | Rain water | Living water |
Flowrate | Min.:10m3/h | Max.:6000m3/h | Â | Â |
Head | Min.:7m | Max.:62m | Â | Â |
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.
• Optional automatic coupling device available to enable simple maintenance and servicing.
• Mild steel outlet pipe installation with flanged connections as standard.
• Optional soft outlet pipe installation available to allow quick and simple mounting and removal when required.
• Optional fixed dry installation available with external cooling water.
