general information

The Multiquip Model ST3020B1 and ST3020BCUL submersible pumps are designed to pump water and is used for the draining (dewatering) of well casings construction sites, coffer dams, manholes, transformer vaults and excavations.

It's slim design (only 6.7 inches in diameter) allows it to fit easily inside 8-inch casings and eliminates the need for larger, more costly casings. The pump is powered by a 2-HP, 230-volt, single-phase motor for easy starting with a 6,000-watt generator.

This rugged submersible pump is loaded with features such as:

„„THERMAL OVERLOAD PROTECTION - automatically shuts off the motor should it reach an unsafe operating temperature.

„„HEAVY-DUTY LIFTING HANDLE - provides and convenient and safe location to attach a lifting device.

„„STRAIN-RELIEF PROTECTOR - provides added safety in the event the operator should try lifting the pump from the electrical cord.

„„REPLACEABLE DISCHARGE PORT - provides easy maintenance and lower repair costs.

„„DOUBLE OIL-LUBRICATED SEAL - provides positive lubrication if the pump should be left running dry. This helps prevent damage in the event the pump is run dry for short periods of time.

„„DUCTILE IRON IMPELLER - for abrasion resistance and extended life. The high-chrome ductile iron material minimizes wear.

„„CORROSION-RESISTANT STAINLESS-STEEL

SHAFT - simplifies maintenance

If the pump was used to pump water containing mud, silt, use clean water to flush out the pump after each use.

DO NOT allow the pump to run dry for an extended period of time, as this will damage the pump. During maintenance, dry running is permissible but only for a few seconds.

NEVER lift the pump by its electrical power cord. ALWAYS lift the pump by its carrying handle or attach a rope to the carrying handle.

A pump fully submerged in liquid will not freeze, unless the liquid freezes. DO NOT allow a partially submerged pump to freeze. The expansion of water freezing in the volute may crack the pump, causing expensive repairs. If there is any danger of the pump being subjected to freezing temperatures, Lift the pump from water and allow it to drain thoroughly.

If the pump jams or the pump rotor locks for any reason, disconnect the pump from the power source immediately. Allowing the pump motor to cycle ON and OFF under an overload condition can burn out the motor.

When replacement of nuts and bolts is required, use only recommended parts as referenced in the parts section of this manual. This pump uses metric threads. DO NOT use English measurement threads.
