ST-4125D/ST-6125D SUBMERSIBLE PUMPS — OPERATION AND PARTS MANUAL — REV. #1 (06/12/08) — PAGE 9 ST-4125D/ST-6125D — GENERAL INFORMATION The Multiquip Model ST-4125D and ST-6125D submersible pumps are designed to pump water. These pumps work best when faced with high head applications where you need an appreciable flow. The ST-4125D and ST-6125D submersible pumps have dual voltage, easily switched between 230 and 460 volts. These pumps have a heavy-duty cast iron body that is very durable and able to withstand rough handling. The ST-4125D comes with NPT threads for standard hose connections while the ST-6125D is equipped with 6-inch flange fittings. The mechanical seal of these pumps operates within an oil filled chamber that provides positive lubrication. This helps prevent damage in the event the pump is run dry for short periods of time. PAGE 10 — ST-4125D/ST-6125D SUBMERSIBLE PUMPS — OPERATION AND PARTS MANUAL — REV. #1 (06/12/08) ST-4125D/ST-6125D — SUBMERSIBLE PUMP COMPONENTS 6 5 5 4 6 4 ST-4125D SUBMERSIBLE PUMP 3 3 ST-6125D SUBMERSIBLE PUMP 2 2 7 7 1 1 8 8 ST-4125D ST-6125D Figure 2. Submersible Pump Components Figure 2 shows the location of the basic components, for the ST-4125D and ST-6125D 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. Volute/Impeller – Impellers are constructed of cast ductile iron to minimize wear and prolong service life. 3. Electric Motor – The ST-4125D pump utilizes a 60 Hz, three-phase, 230/460 VAC, 10 HP electric motor and the ST-6125D pump utilizes a 60 Hz, three-phase, 230/ 460 VAC, 15 HP electric motor. Consult with a licensed electrician before connecting motor to a power source. Observe all city and local safety codes. 4. Discharge Port – Connect a 4-inch hose (ST-4125D) or 6-inch hose (ST-6125D) to this port. Remember to adequately support the discharge hose to avoid stress on the pump. 5. AC Power Cable – These pumps are supplied with a 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. 6. Eye Bolts – Always lift the submersible pump by the eye bolts using a chain and lifting device capable of lifting about 400 lbs. NEVER lift the pump by its power cord! 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. 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. 8. 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. ST-4125D/ST-6125D SUBMERSIBLE PUMPS — OPERATION AND PARTS MANUAL — REV. #1 (06/12/08) — PAGE 11 Float Switch Theory ST-4125D/ST-6125D — FLOAT SWITCHES Float Switch (Dual) There is a tilt-sensitive mercury switch hermetically sealed within each float. As the liquid level (water) rises or falls, the float changes its angle until the mercury switch makes (close) or breaks (open) the circuit. The length of cord between the float and point of attachment determines the amount of water to be pumped. Contact Multiquip sales department to order float switches. EXTERNAL 3-PHASE (230 OR 460 VOLT) POWER SOURCE CIRCUIT BREAKER Float switches (Figure 3) are used for the unattended operation of the submersible pump. The ST-4125D and ST-6125D pumps require the use of a control box to perform this function. Shown in Figure 3 is an example of a dual float control switch application. The Models ST-4125D and ST-6125D submersible pumps require one each of the Model SW-1WOPA float type mercury switches. These switches have a pumping range level between 5.5~18 feet (1.67~5.5 meters). All float switch connections are bare wire (no plug). The ST-4125D/ST-6125D uses the CB12 control box for 230V and the CB14 control box for 460 V when float switches are required for the job application.

This means that power is being supplied to the control box. Figure 10. Control Box Power ON Indicator 4. In the manual mode the pump will run continuously. Pay close attention when running the pump in this mode. DAMAGE to the pump may occur if pump is not immersed in water. 5. To operate the pump automatically (float switches), place the 3-position operation switch in the AUTO position (Figure 11). Figure 11. Manual-Off-Auto SW. (Auto Position) 6. In the AUTO mode the pump will run as long as there is a sufficient amount of water. This amount is determined by the setting of the float switches. The stop float switch contacts will open when the water level is low and power will be removed from the pump's motor. Once the water level has risen back to the appropriate level the start float switch contacts will close and power will be restored to the pump's motor. 1. Place the 3-position operation switch on the control box to the OFF position (Figure 13). Figure 13. Manual-Off-Auto SW. (OFF Position) 2. Verify that the control box power ON light is OFF. 3. Turn the circuit breaker or quick disconnect switch to the OFF position.

DO NOT stand in water when connecting the pump's power cord into a voltage source. The possibility exist of electrical shock, electrocution and possibly death! 3. If all of the pump's electrical requirements have been met, insert the power plug on the pump into the power source receptacle. 4. Wait a few seconds and water should begin to flow from the discharge hose. 5. If water is not flowing from the discharge hose or not flowing freely after a few minutes, remove the power from the pump and check the system for leaks. ST-4125D/ST-6125D — OPERATION 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. Remem ber 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 chain and lifting crane, lift the pump up from its current position. Remove the discharge hose from the dis charge port on the pump. 3. Remove all power cables and float switches from the control box. Place cables and float switches in a suitable container where they will not get damaged. 4. If the pump was used to pump mud, grit or silt, flush vigorously with clean water. 5. Remove the pump from the water. Wipe off any mud or debris that might have attached itself to the pump. 6. Store pump in a clean dry place away from dirt and debris.

If oil level is low fill with SAE 10 weight non-detergent To check the oil level of the mechanical seal perform the following: 1. Lay the pump (Figure 17) 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. 4. While checking the hydraulic oil level, also check the condition of the hydraulic oil in the seal cavity . Block the opening with a finger and roll pump to one side to drain oil into a small transparent container. If oil is cloudy or has water in it, drain oil from pump cavity and replace hydrau lic oil. Check the seal for wear damage. LAY PUMP FLAT ON ITS SIDE hydraulic oil (i.e. Shell Turbo 32 or equivalent). Fill oil cavity 75% to 85% full (allow air space for expansion). Pump oil cavity capacity is approximately 180 cc. IMPELLER 1. Make sure the clearance between the impeller and the friction disk is approximately .012 - .020 inches (.304 - .508 mm.) 2. If impeller is defective or badly worn, replace impeller imme diately. REMOVE FILL PLUG, AND VISUALLY INSPECT THAT OIL CAVITY IS FULL ENOUGH TO COVER SEAL SPRING. FILL TO 75-80% CAPACITY (APPROXIMATELY 180 CC.) FILL WITH 10 WEIGHT NON DETERGENT HYDRAULIC OIL. USE SHELL TURBO 32 OR EQUIVALENT. CHECK HYDRAULIC OIL EVERY 300 HOURS. CHANGE EVERY 6 MONTHS OR AS NEEDED. Figure 17.
