ST2037, 47, 47B, 38P, 40T SUB. PUMP — GENERAL INFORMATION

Introduction

The Multiquip Model ST2037, ST2047, ST2047B, ST2038P, and ST2040T submersible pumps are designed to pump water and is used for the draining (de-watering) of swimming pools, well casings construction sites, cofferdams, manholes, transformer vaults and excavations.

A Nitorile rubber over steel impeller is attached to the output shaft of a 1HP 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 located at the top of the pump 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 located on top of the pump. 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.

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 pump 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 measurement threads.

Control Box Installation Warnings

WARNING

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 buildup of mud, grit, silt or debris. If this condition is present, install the pump on a platform before operating.

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.

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

Figures 2 shows the location of the basic components, for the ST2037, ST2047, ST2047B, ST2038P, and ST2040T submersible pumps. Listed below is a brief explanation of each component.

1. Strainer Base – This strainer base is made of electrocating steel which is resistant to hardware corrosion. DO NOT pump large objects or debris with this pump. This pump is for pumping water only. For de-watering purposes, always place the strainer base on a platform.

2. Volute/Impeller – Impellers are constructed of Nitorile Rubber to minimizes wear and prolong service life.

3. Electric Motor – These submersible pumps utilize a 60 Hz, single-phase, 115 VAC, 1 HP electric motor. Consult

licensed electrician

with a power source. Observe all city and local safety codes.

4. Discharge Port – Connect a 2-inch hose to this port. Remember to adequately support the discharge hose to avoid stress on the pump.

before connecting motor to a

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 a 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 Seal Oil – 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.

9. Mechanical Seal Oil 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.

ST2040T

5. AC Power Cable – This unit is supplied with a 25 ft. (7.6

meters) or 50 ft. (15.2 meters) AC 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.
