Davey DT37G Submersible Grinder Pump

Grinder pumps are typically used for heavy duty shredding with a grinding ring at the input point, and have an open impeller, centrifugal design preventing blockages of the pump or pipework. A 304SS grade steel for the shaft, motor shell and fasteners ensure a long service life.

INSTALLATION & PRIMING

  • Use a rope to position and retrieve the pump. Do not lower or retrieve
    the pump using the power lead as this may damage the cable entry
    seals, causing water leaks and unsafe operation.
  • Do not use this product for recirculating or filtering swimming pools,
    spas, etc. While these pumps are built to high safety standards, they
    are not approved for installations where people will be in the water
    while they are operating.
  • Do not pump abrasive materials. Sand and grit in the water being
    pumped will accelerate wear, causing shortened pump life.
  • Make room for the float switch to operate. Automatic models have a
    float switch to turn them on when the water level rises and turn them
    off again when it has been pumped down to the safe operating level of
    the pump. If the float switch is not free to rise and fall, correct pump
    operation may not be possible.
  • Don’t run your pump dry. Non-automatic models must be switched off
    manually or by way of an external float/level switch when the water
    level is reduced to the top of the pump housing.
