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.

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. 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. 1.
float switches Float Switch Theory Design Features 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. Constructed of rigid, durable ABS polymer ultrasonically welded. The all-steel mercury switch is held by positioning pins.
float switch (piggy-back) Float Switch 2. Place the cord into the clamp as shown in Figure 6 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 ST-2010 series 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.
float switch (control box) Control Box For special remote pumping applications of the submersible pump, a control box (Model CB3 - for ST2010, ST2010A, ST2010CUL, and ST2010TCUL and Model CB6 - for ST2010B) 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). Figure 7.

operation Hose Connections Connect a 2-inch hose to the discharge port on the pump as shown in Figure 9. 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.
control box installation DANGER The ST2010 Series submersible pumps are designed to work with a control box. The control box contains the necessary electronics (float switch connections) to operate the pump. Remember the control box contains hazardous voltages. Disconnect all sources of power before installing or servicing.
control box installation Connecting AC Power to the Control Box 1. The AC power cord (input) should have three wires. Each wire is color coded. The colors are WHITE, BLACK and GREEN. 2. Remove the AC input connector housing from the control box, then route the power cord through the cable gland on the control box. 3. Connect the AC power cord to the contactor as shown in Figure 7 and Table 6. Table 6.
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.
maintenance LUBRICATION To check the oil level of the mechanical seal perform the following: 1. Lay the pump (Figure 12) 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. Shell Turbo 32 or equivalent).
troubleshooting Symptom Pump Fails To Start Pump Fails to Deliver Full Output Water in Seal Oil Troubleshooting (pump) possible problem Solution Check that proper voltage is being supplied to the pump. Also check that there is an adequate Incorrect voltage/amps? amount of current (amps) to run the pump. Check power source circuit breaker. If using float switches check wiring, inspect Check electrical connections? power cord. Blown power fuse? Replace fuse, check cause of blown fuse.
