Industrial Submersible Recirculation Pump

The operation of submersible pumps is similar to that of electric submersible centrifugal pumps. An enclosed electric motor powers the pump as the fluid’s kinetic energy rises. The fluid is subsequently lifted through the pump by this energy’s partial conversion to pressure. The design uses a vertical shaft to rotate the impellers and pressurise fluid. Using mechanical seals is necessary to prevent the electric motor from malfunctioning as the entire unit is submerged in the fluid.

On the other hand, Sulzer recirculation pumps XRCP and RCP are centrifugal propeller types (dynamic/axial flow type) capable of pumping and recirculating large amounts of water at low back pressure. Typically used in wastewater handling and wastewater treatment applications, these pumps’ function is to recirculate sludge or rainwater back to the treatment process. They direct fluid in a straight line parallel to the impeller shaft rather than radially (which is more common in traditional centrifugal pumps).

RECIRCULATION PUMP: ABS RCP

The ABS RCP series consists of recirculation pumps used in handling activated sludge during the denitrification / nitrification process in wastewater treatment plants. These submersible pumps are also designed for large flow and low head conditions between 0.1 and 1.8 metres. ABS RCP pumps are more economical compared to axial flow pumps as they do not need inflow chamber and large rising pipe when installed in tanks.

Pump Design Features

Self-cleaning propeller, 2- or 3-blade, optimized for effective pumping and vibration-free running
Efficient three-phase motor, water pressure-tight encapsulated, protection type IP 68, stator insulation class F = 155°C. Motor shaft and rotor are dynamically balanced
- Economical and reliable design
- Continuous running 24/7
Cable connection area is sealed from the motor, with a water pressure-tight cable inlet, antikink sleeve and strain relief
Double shaft sealing with medium side mechanical seal of pure sintered silicon carbide
Hydrodynamically designed solids deflection ring
DI-electrode for seal monitoring and an indication that an inspection is due
Lubricated-for-life bearings with a calculated life of more than 100’000 operating hours

Full stainless steel version (optional)
Self-cleaning propeller
Silicon carbide (SiC/SiC) mechanical seal protected by means of solid deflection ring
Condition monitoring (temperature, water ingress)
100 000 hour bearing lifetime

The unit is lowered along a guide tube and connected to the pipeline by an automatic coupling system.
