Description

Submersible Close Impeller Pump Working Principle

Submersible close impeller pumps are fwith a closed impeller. The suction opening in the base plate is directly in contact with the fluid to be pumped. The rotation impeller transmits kinetic energy to the fluid which is centrifuged in the ring chamber, where part of the kinetic energy is transformed into pressure energy. The particular design of the impeller optimizes hydraulic efficiency, while allowing the pump to handle muddy fluids containing solids in suspension and short fibers without danger of clogging.

Pumps Installation and Application

The pumps are with aluminum or plastic single vane impellers, and are suitable for pumping liquids containing solids in suspension, including short fibers. The pumps are particularly for handing clean water or sewage, refulgent water, water mixed with mud, groundwater and surface water in areas such as: residential housing blocks, public buildings, multi-storey car parts, car washes etc.

Performance

1.The pumps have the following features:
2.exceptional sturdiness, even under severe working conditions;
3.long and stable performance curves with particularly high efficiency level.
