The QCK series stainless steel submersible pumps are designed for slightly dirty liquid drainage jobs. The pump fits into narrow drainage pits, and the use of stainless steel makes the pumps virtually maintenance free. The strainer, which will allow solids up to 10mm to pass.

Structures:
The pumps are made with a stainless steel pump sleeve and housing, made in one piece. The suction strainer prevents the passage of large solids while ensuring a slow flow into the pump. As a results, most impurities will be deposited outside the pump.

Pumped liquids:
QCK pumps are suitable for pumping of:
Clean, non-aggressive water
Grey wastewater without solid particles or fibers
Drainage water with solids up to 10 mm size

Impeller
The QCK impeller is made of stainless steel. It is of a semi-open type with L-shaped impeller blades. The blades curve backwards in order to reduce any harmful effects from solid particles and to reduce power consumption.

Motor
The QCK motor is an asynchronous dry motor. The pumped liquid cools the motor. Welding hermetically seals the motor unit and no filling compounds have been used.
At the top of motor, single-phase pumps have a capacitor housing with capacitor and sockets for the motor cable and float switch. Oil is used as a barrier fluid between the pumped liquid and the motor unit.
Enclosure class: IP68
Insulation class: F

Installation
The QCK pumps are available for manual or automatic operation. For manual on/off operation, the pump is supplied without a float switch.
For automatic operation, the pump can be supplied with a built-in float switch (single phase models). Three phase models can be supplied with a separate float switch and control box.
Pumps fitted with float switches can also be used for manual on/off operation if the float switch is fixed in an upwards-pointing position.
The pumps can be used in a vertical, horizontal or titled position, as long as the discharge port remains the uppermost part of the pump.

Application
The QCK pumps are suitable for following application:
Groundwater lowering
Pumping from drainage pits
Pumping from surface water pits with inflow from roof gutters, shafts, tunnels etc.
Emptying of ponds, tanks etc.
