general information The Multiquip Model ST41230/ST41460 and ST61230/ ST61460 submersible pumps are designed to pump water. These pumps work best when faced with high head applications where you need an appreciable flow. The pumping of flammable, toxic, corrosive, abrasive liquids is strictly forbidden. These pumps are best suited for clear water applications where maximum size of solids (debris) does not exceed 0.6-inches (15.2 mm).

Submersible Pump Components Figure 2 shows the location of the basic components, for the submersible pumps. Listed below is a brief explanation of each component. 1. Strainer Base – This strainer base is made of stainless steel which is resistant to hardware corrosion. For dewatering purposes, always place the strainer base on a platform. 2.
float switches Mechanical Float Switch Design Features Mechanically activated float switches offer a reliable low current control for dewatering applications. Float switch housings are constructed of high-impact, corrosion resistant polypropylene with mechanically activated, snap action contacts. How It Works The mechanical float switch control will turn ON (close) when the float tips 45° above -horizontal, indicating a high level, and turns OFF (opens) when the float switch drops 45° below horizontal.
float switches Float Switches Mounting The Float Switches For unattended operation of the submersible pump two single float switches (Model SW-1WOPA) will be required. These float switches can be connected directly to a control box (bare wires) and will allow the pump to turn on and off depending on the length of the tether. 1. Determine the required cord tether length as shown in Figure 3 and Table 3. 2. Place the cord into the clamp as shown in Figure 6. 3.
float switches Control Boxes For remote pumping applications, all four model submersible pumps will require a control box (Figure 7). CAUTION! HIGH VOLTAGE! For each model submersible pump there is an associated control box. Reference Table 4 for the desired control box and applicable heater. The heater size is determined by the the full load amps the pump will draw.
control box installation Control Box Installation CONTROL BOX MOUNTING The following procedure outlines the steps for connecting the pump to a control box. Mount the control box in an upright vertical position. Make sure the control box is securely fastened to a flat surface, that is free of dust, dirt, moisture or any elements that may contaminate or erode the electronic components of the control box. DANGER Each submersible pump is designed to work with a control box.
control box installation Connecting SW-1WOPA Float Switches to Control Box 1. Remove the float switch input connector housing, then route the float switch wires through the cable gland on the control box. Attach the wires of the float switch to the terminal block as indicated by Table 6 and Figure 8. Table 6.

operation Pump Placement LOWER LOWER 1. Attach a suitable lifting chain to the eye bolts or lift handle (Figure 9) on the pump. Use a crane, or similar lifting device and lower the pump into place. For applications where there is an excessive amount of mud, grit or silt, the use of a support platform is desirable. 2. Make sure the pump is always placed in an upright position, not tilted (Figure 10). Never position the pump directly on a soft, loose bottom.
operation Control Box Operation (Manual Mode) Reset Button 1. From the voltage source, set the circuit breaker or quick disconnect switch to the ON position. 1. When the electronic overload module detects an overload condition, the pump will shut down. Check the pump and correct the cause of ther overload. 2. For manual operation of the pump, place the 3-position operation switch (Figure 11) on the control box in the MANUAL position. 2.
maintenance Lubrication Inspecting Lubrication Oil (Mechanical Seal) To check the lubrication oil level of the mechanical seal perform the following: 1. Block the oil fill opening with a finger and roll pump to one side to drain (Figure 17) oil into a small transparent container. Checking Lubrication Oil Level 1. Lay the pump (Figure 16) on its side with the oil plug facing upwards. 2. If oil is cloudy (milky) or has water in it, indicates that mechanical seal is defective or worn.
maintenance Impeller Removal Refer to the the following procedure and Figure 18 for the removal of the impeller. ST61230/ST61460 ST41230/ST41460 1. Remove oil screw and gasket from the oil fill chamber port. Drain oil from oil chamber as referenced in Figure 18. 2. Remove the four hex nuts and lock washers that secure the base plate to the inlet plate. 3. Remove base plate, inlet plate, o-ring and strainer. 4. Next, remove the four bolts and lock washers that secure pump casing to the seal bracket. 5.
maintenance Water Tank Storage NOTICE If an installed pump (immersed in water) has not been in operation for a long period of time, check the insulation resistance and run the pump for 30 minutes every month. Insulation resistance is moisture and temperature sensitive. When temperature increases, insulation resistance decreases, and vice versa.

troubleshooting Table 9. Pump Troubleshooting SYMPTOM Pump Fails To Start Pump Fails to Deliver Full Output Water in Mechanical Seal Oil POSSIBLE PROBLEM SOLUTION Incorrect voltage/amps? Check that the proper voltage, 230 or 460 VAC, 60 Hz, 3-phase is being supplied to the pump. Also check that there is an adequate amount of current (amps) to run the pump. Check power source circuit breaker. Check electrical connections? If using float switches check wiring, inspect power cord.
