Sewage Pumps

The free vortex type retracted open impellers fitted to PVXC pumps are suitable for handling dirty water, sewage, effluent water, water mixed with mud, liquids containing air or gas as well as treated and putrid mud.

The pumps are particularly well suited to installation and operation in sewers, excavation sites, wells, channels, underground car parks and other subterranean locations. Manufactured in thick cast iron our pumps are built to last with superb longevity and abrasion resistance, and come supplied with delivery flange, discharge connector and guide rails for fixed installation.

Structural Characteristics

• Cast iron open vortex IMPELLER
• AISI 304 stainless steel motor shaft
• Screws in contact with fluid in Stainless steel. (Optional stainless steel lifting eye)
• DOUBLE SEAL SYSTEM Ceramic/silicon carbide on the pump side and lip seal on the motor side (with barrier oil chamber to lubricate and cool the sealing surfaces in the absence of water).
• Sealed induction MOTOR : with double impregnated class F winding (ensuring extended motor life and wide range of use), designed for continuous duty, even with the pump partially submerged (min. 350mm for PVXC/50 models; 400mm for PVXC/70) A thermal cutout device (motor protector) is incorporated in single phase models.
• Three phase motors have three thermal cut-outs in the windings, connected in series with the supply cable. They must be correctly connected to the pump control panel by the user.
• PROTECTION IP 68.
• CONTROL BOX (single phase models only) with capacitor and manual reset, IP64
• SUPPLY CABLE -
  Single phase : 10 metres of neoprene HO7 RN-F submersible cable
  Three phase: 10 metres of neoprene FG5 OK 4x1.5mm + 2 x 0.5mm
• CONSTRUCTION AND SAFETY STANDARDS in compliance with EN 60 335 -1, CEI 61-150, EN 60034-1, IEC 34-1, CEI 2-3
