OPERATION
5. When pumping is complete, set the hy draulic control
valve to the “OFF” posi tion. Lift the trash pump from the
work area using the rope or cable to avoid damage to the
hoses or couplers.
Observe the following for trash pump protection and
care.
6. The trash pump must maintain a mini mum impeller
speed in order to move solid particles through the pump.
While pumping liquids containing large solids, monitor the
fl ow from the outlet of the fi re hose. If it begins to slow, turn
off the hydraulic power source and lift the trash pump from
the work area. Disconnect the hydraulic hoses and clean at
the water hose and the pumping chamber.
Pumping liquids with a solids-to liquid ratio greater
than 30 per cent solids to 70 percent liquid will cause
accelerated impeller wear.
7. To maintain optimum performance, it is good practice to
periodically inspect the impeller for wear or damage. This
is especially important following the pump ing of liquids
containing sharp, abrasive solids.
COLD WEATHER OPERATION
If the trash pump is to be used during cold weather, preheat
the hydraulic fl uid at low power source speed. When using
the nor mally recommended fl uids, fl uid should be at or
above 50°F/10° C (400 ssu/82 centistokes) before use.
Damage to the hydraulic system or pump motor seals can
result from use with fl uid that is too viscous or thick.
