Water Pump with Grinder 2900W / 2" — Kraft&Dele KD757
The KD757 is a submersible electric pump designed for pumping clean water, dirty water and sewage containing solid particles up to 7 mm. Fitted with a grinder and an automatic float switch, it can operate without constant supervision.
Product features
Solids grinder
The built-in grinder allows liquids containing solid particles up to 7 mm to be pumped — such as leaves, small twigs, mud, sludge and organic suspensions. This eliminates the risk of the pump clogging when working with heavily contaminated water.
Automatic float switch
The float monitors the liquid level in the sump and automatically switches the pump off when it drops below a safe level. This prevents dry running, which leads to overheating and damage to the seals and impeller.
Thermal cut-out
The built-in thermal cut-out switches the pump off if the permissible operating temperature is exceeded. The unit requires breaks in operation: after every 30 minutes of continuous running, a 15-minute break is required to let the motor cool down.
2" outlet and fire hose coupling
The 2" (52 mm) outlet provides a high flow rate and allows standard industrial hoses to be connected. A fire hose coupling is included, which shortens preparation time.

Use and maintenance
Continuous operation limits
The pump is designed for intermittent operation — the maximum continuous running time is 30 minutes, after which a 15-minute break is required. Exceeding this time may lead to overheating of the motor. The temperature of the pumped liquid must not exceed 40°C.
Hose connection and compatibility
The 2" (52 mm) outlet port is compatible with standard industrial and fire hoses. A fire hose coupling is included. Before buying a hose, check that the coupling is compatible with your existing equipment.
Maintenance after use with sewage
After every use with sewage or heavily contaminated water, rinsing the pump with clean water for a few minutes is recommended. This prevents deposits building up inside the housing and on the impeller, which could reduce the pump's performance.
