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.
ST2037, 47, 47B,38P, 40T SUB. PUMP — COMPONENTS ST2037, ST2047, ST2047B ST2038P ST2040T 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. 2. 3. 4. 5. 6. Carrying Handle – Always carry the submersible pump by its handle. NEVER! carry the pump by its power cord.
ST2037, 47, 47B, 38P, 40T SUB. PUMP — FLOAT SWITCHES Float Switch Theory Design Features Mercury monitoring is a mercury-switch actuated, liquid level 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 electromechanical switches most often relied upon in the past. Constructed of rigid, durable ABS polymer ultrasonically welded.
ST2037, 47, 47B, 38P, 40T SUB. PUMP — FLOAT SWITCH (PIGGY-BACK) Float Switch Single or dual control float switches (Figure 6) can be used for the unattended operation of the submersible pump. When using the piggy-back power configuration (plug), the pumps DO NOT require the use of a control box. In this configuration (piggy-back), the SW-1 (single float switch) or SW-2 (dual float switch) are required. The illustration below is an example of a single float switch application. Mounting The Float Switch 1.
ST2037, 47, 47B, 38P, 40T SUB. PUMP — FLOAT SWITCH (CONTROL BOX) Control Box (CB3) For special remote pumping applications of the submersible pump, a control box (Model CB3) may be required. This water resistant control box provides watertight housing and glands to prevent water from leaking into the box, and a float switch interface. When using the CB3 control box, only the SW-1WOP float switch (2) can be used (no plug, bare wires). Shown below (Figure 7) is a wiring layout of the CB3 control box.
ST2037, 47, 47B, 38P, 40T SUB. PUMP — OPERATION Hose Connections 1. Connect a 2-inch hose to the discharge port on the pump as shown in Figure 8. Make sure that the hose is attached correctly to the discharge port. Pump Power Connections (Piggy-Back Cord Only) 1. Make sure the circuit breaker supplying power to the pump is in the OFF position. 2. Connect the float switch or switches to the AC power receptacle as shown in Figure 6. Attaching Lifting Rope 1.
ST2037, 47, 47B, 38P, 40T SUB. PUMP— CONTROL BOX INSTALLATION DANGER The ST2037, ST2047, ST2047B, ST2038P, and ST2040T submersible pumps are also designed to work with a control box (Model CB3). This control box contains the necessary electronics (float switch connections) to operate the pump. Remember this control box contains hazardous voltages. Disconnect all sources of power before installing or servicing.
ST2037, 47, 47B, 38P, 40T SUB. PUMP— CONTROL BOX INSTALLATION Connecting AC Power to the Control Box 1. 2. 3. The AC power cord (input) should have three wires. Each wire is color coded. The colors are WHITE, BLACK and GREEN. Remove the AC input connector housing from the control box, then route the power cord through the cable gland on the control box. Connect the AC power cord to the contactor as shown in Figure 7 and Table 6. 2.
ST2037, 47, 47B, 38P, 40T SUB. PUMP — CLEAN-UP AND MAINTENANCE Pump Shut-Down/Clean-up For Model ST2037, ST2047, ST2047B and ST2038P: 1. Remove the power from the pump by turning off the circuit breaker or switch that provides power to the pump. Remember to make sure that hands are dry (not wet), and feet are not standing in water when removing disconnecting power from the pump. 1. Position pump upside down. 2. Using the lifting rope, lift the pump up from its current position.
