Desing Details pump rwcp / rwcn
Volute pump casing with axial suction and radial impulsion.
Three variants of single stage impeller: semi-open (A), channel (C) or vortex (V).
The RWCP is equipped with a discharge pipe to the outside of the base plate.
Pump is for vertical installation in non pressurized tanks as standard. Special executions for very low pressurized tanks are available on demand.
Shaft Seal
Lip seal is supplied as standard. Single mechanical seal (cartridge or non cartridge) or packing can be supplied as options.
Bearings / Lubrication
External angular contact ball bearings, grease lubricated, with external grease nipples, in a bearing bracket above the plate.
TFM (Special PTFE, Graphite charged) product lubricated friction bearing bushes in pump cover and intermediate column bearing supports. In case of poor lubricant, abrasives or solids, an external suitable fluid (e.g. fresh clean water) must be provided. Optionally an electric driven grease pump can be supplied.
Coupling
Flexible, rubber plug type coupling. Other types, upon request.
Coupling Guard: Transparent plastic protections are supplied as standard. Metallic protections can be supplied as option.
