ST-1500 SERIES SUB. PUMP — GENERAL INFORMATION Introduction The Multiquip Model ST-1500 series submersible pumps are designed to pump water and is used for the draining (dewatering) of swimming pools, well casings construction sites, cofferdams, manholes, transformer vaults and excavations. A cast iron ductile type impeller is attached to the output shaft of a 0.5 HP (ST-1503A) or 0.3 HP (ST-1503CUL) electric motor which provides adequate power for general purpose pumping.

ST-1500 SERIES SUB. PUMP — COMPONENTS Figure 2. Submersible Pump Components Figures 2 shows the location of the basic components, for the ST-1500 series submersible pumps. Listed below is a brief explanation of each component. 1. 2. 3. 4. Strainer Base – This strainer base is made of stainless 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.

ST-1500 SERIES 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.
PAGE 13
ST-1500 SERIES SUB. PUMP — FLOAT SWITCH (PIGGY-BACK) Float Switch Single or dual control float switches can be used for the unattended operation of the submersible pump. When using the piggyback power configuration (plug), the ST-1500 series pumps DO NOT require the use of a control box. In this configuration (piggyback), the SW-1 (single float switch) or SW-2 (dual float switch) are required. Figure 6 is an example of a single float switch application. Mounting The Float Switch 1.
PAGE 14
ST-1500 SERIES 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.

ST-1500 SERIES SUB. PUMP — OPERATION Hose Connections 1. Connect a 2-inch (ST-1503A) or 1.5-inch (ST-1503CUL) 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.
PAGE 16
ST-1500 SERIES SUB. PUMP— CONTROL BOX INSTALLATION DANGER The ST-1500 series 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.

ST-1500 SERIES 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.
PAGE 18
ST-1500 SERIES SUB. PUMP — CLEAN-UP Pump Shut-Down/Clean-up 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. 2. Using the lifting rope, lift the pump up from its current position. Remove the discharge hose from the discharge port on the pump. 3. Remove all power cables and float switches from the control box.

ST-1500 SERIES SUB. PUMP — MAINTENANCE LUBRICATION To check the oil level of the mechanical seal, perform the following: 1. Lay the pump (Figure 11) on its side with the oil plug facing upwards. 2. Remove oil fill plug. 3. Visually inspect oil plug hole to verify that oil cavity is full enough to cover seal spring. Check every 300 hours, change hydraulic oil every 6 months (1,000 hours) or as needed. 5. If oil level is low fill with SAE 10 weight non-detergent hydraulic oil (i.e.

ST-1500 SERIES SUB. PUMP — TROUBLESHOOTING Practically all breakdowns can be prevented by proper handling and maintenance inspections, but in the event of a breakdown, use Table 8 (Pump Troubleshooting) as a basic guideline for troubleshooting the pump. If the problem cannot be remedied, contact Multiquip's service department. TABLE 8. PUMP TROUBLESHOOTING SYMPTOM POSSIBLE PROBLEM SOLUTION Incorrect voltage/amps? Check that proper voltage (115 VAC, 60 Hz, single-phase ) is being supplied to the pump.
