GENERAL INFORMATION
INTRODUCTION
The Multiquip Model ST-2010 submersible pump is designed to pump water and is used for the draining (de­watering) of well casings construction sites, cofferdams, manholes, transformer vaults and excavations. The ST­2010TCUL is designed for heavily debris-laden water and the 2-inch discharge port can handle solids up to one inch in diameter.
A cast ductile iron type impeller is attached to the output shaft of a 1 HP electric motor which provides adequate power for general purpose pumping. This submersible pump is supplied complete with an electric power cable, and a discharge port which accepts a 2-inch hose.
This pump is ideal for portability because of its light weight and carrying handle. For reliability and long life, a mechanical seal provides shaft sealing, with an oil chamber separating the pump section from the motor.
The pump when in use, should be installed as free standing (upright position) on its strainer base. A 2-inch discharge hose (not supplied) should be connected to the discharge port. The discharge hose should be adequately supported to avoid stress on the pump.
For maximum water flow, the discharge hose should be kept as short as possible, and with minimum elevation above the pump. Remember as the length and/or height of the discharge hose is increased, the flow of water will be reduced. Also any reduction in the hose size, and any fittings such as valves or outlet nozzles, will restrict the water flow.
To avoid back-siphonage when the pump is switched off, ensure that the end of the discharge hose is installed above the water level at the final discharge point.
When the pump is switched off, the water remaining in the hose will run back through the pump. This can be avoided by placing a non-return valve in the hose nearest the pump.
This pump must always be positioned on a platform in an upright position. NEVER operate the pump by a suspended rope. To prevent large solids from entering the pump, install a wire mesh screen or similar barrier around the pump.
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, 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.
WARNING
Explosion or Fire Hazard exists if this pump is used with flammable liquids. DO
NOT use this pump with flammable liquids. DO NOT install this pump in hazardous
locations as defined by the National Electrical Code, ANSI/NFPA 70.
NEVER use this submersible pump to pump flammable liquids or operate in a explosive or flammable environment.
Avoid using this pump in conditions where mud, grit, silt or other debris are present. These conditions could cause blockage and cause excessive pump wear.
DO NOT install the pump directly into an area where there is a heavy build-up of mud, grit, silt or debris. If this condition is present, install the pump on a platform before operating.
PAGE 10 —ST2010 SERIES SUBMERSIBLE PUMP • OPERATION AND PARTS MANUAL — REV. #3 (12/07/12)
Failure to follow the above referenced precautions could result in serious injury or death! Replace pump cord immediately if cord becomes damaged or severed. This pump must be installed in accordance with National Electric Code ANSI/NFPA 70 so as to prevent moisture from entering or accumulating with the boxes, conduit bodies fittings, float housing or cable.

Figure 2. Submersible Pump Components
Figure 2 shows the location of the basic components for the ST2010 series submersible pumps. Listed below is a brief description of each component.
1. Strainer Base — Made of chrome-plated steel which is resistant to hardware corrosion. DO NOT pump large objects or debris with this pump. This pump is for pumping water only. Always place the strainer base on a platform.
2. Volute/Impeller — Volute is constructed of cast iron and impeller is made of cast ductile iron to minimize wear and prolong service life.
3. Electric Motor — All ST2010 series submersible pumps utilize a 60 Hz, single-phase, 1.0 HP electric motor. The ST2010, ST2010A, ST2010CUL and S-2010TCUL operate at 115 VAC while the ST2010B operates at 230VAC. Consult with a licensed electrician before connecting motor to a power source. Observe all city and local safety codes.

power cable. Always check the cable for signs of wear. NEVER use a defective power cable. Replace the cable immediately if the cable is worn or defective.
6. Carrying Handle — Always carry the submersible pump by its handle. NEVER carry the pump by its power cord. Carrying or lifting the pump by the power cord will cause undue stress on the cord and ultimately the cord will become dislodged from the pump.
7. Thermal Overload Protection — This pump is equipped with thermal overload protection device that will shut down the motor in the event of high operating temperatures. The motor will automatically restart once the temperature returns to an acceptable operating temperature.
8. Mechanical Oil Seal — This oil-filled seal provides lubrication when running the pump dry. NEVER run the pump dry. Running the pump dry will cause severe damage to the pump.
4. Discharge Port — Connect a 2-inch hose to this port. Remember to adequately support the discharge hose to avoid stress on the pump.
5. AC Power Cable — This unit is supplied with an AC
ST2010 SERIES SUBMERSIBLE PUMP • OPERATION AND PARTS MANUAL — REV. #3 (12/07/12) — PAGE 11
9. Mechanical Oil Seal Plug — Remove this plug to check and add hydraulic oil (Shell 32 or equivalent) to the oil cavity. This oil protects the mechanical seal. Oil cavity should be full enough to cover seal spring.
FLOAT SWITCHES
FLOAT SWITCH THEORY
Mercury monitoring is a mercury-switch actuated, liquid­level control that has proven to be more economical and longer lasting than other types of liquid-level control systems, easily replacing and improving upon diaphragm switches, air bubble systems and electro-mechanical switches most often relied upon in the past.
HOW IT WORKS
There is a tilt-sensitive mercury switch hermetically sealed within each float. As the liquid level (water) rises or falls, the float changes its angle until the mercury switch makes (closed, Figure 4) or breaks (open, Figure 5) the circuit. Maximum pumping range is 120 degrees. See Figure 3 below.
DESIGN FEATURES
Constructed of rigid, durable ABS polymer ultrasonically welded. The all-steel mercury switch is held by positioning pins. Interior is filled with cell foam.
 Suitable for most liquid environments.
 Hermetically sealed.
 Thick-walled non-corrosive PVC plastic enclosure.
 Pressure tested to 60 ft. (18.2 meters).
 Mercury switch reliability, proven to 500,000 cycles.
 Standard SJO, 16-gauge, 2 conductor cord (20 ft./6.09 m).
Figure 3. Pumping Range (Float Switch)
PUMPING RANGE
The pumping range of the pump is determined by the float switch tether cord. Use Table 3 as guide line to determine your required pumping range. Pumping ranges are based on non-turbulent conditions. Range may vary due to water temperature and cord shape. Please note as the tether length increases, so does the variance of the pumping range.
