OPERATION

PREPARATION PROCEDURES

CHECK POWER SOURCE

1. Using a calibrated flow meter and pressure gauge, make sure the hydraulic power source develops a flow of 7–12 GPM/26–45 Ipm at 1000–2000 psi/70– 140 bar.
2. Make certain that the power source is equipped with a relief valve set to open at 2100 psi/145 bar maximum.
3. Make certain that the power source return pressure does not exceed 250 psi/17 bar.
4. Make sure the trash pump inlet is clear of debris.
   Remove any obstruction before operating. See “Cleaning the Pumping chamber” on page 10.

CONNECT HOSES

1. Wipe all hose couplers with a clean lint free cloth before making connections.

2. Connect the hoses from the hydraulic power source to the couplers on the trash pump or trash pump hoses. Connect the return hose first and disconnect it last to minimize trapped pressure within the motor.
   Note: If uncoupled hoses are left in the sun, pressure increase inside the hoses might make them difficult to connect. Connect the free ends of the hoses together

3. . Observe the arrow on the couplers to ensure that the flow is in the proper direction. The female coupler on the trash pump is the inlet (pressure) coupler.

PUMP OPERATION

1. Observe all safety precautions.
   Note: The SM50 is not designed for use with a suction pipe inlet. The diameter of the suction screen at the bottom of the pump provides maximum pump efficiency. Reducing the size of this inlet will greatly reduce pump performance.

2. Connect a hose fitted with a 3 inch/76.2 mm female camlock coupler to the pump outlet fitting. Make sure the fitting is securely tightened. For best performance, keep the hose as short as possible and lay it out to avoid sharp bends or kinks.

3. Lower the pump into the liquid to be pumped. Locate the outlet end of the discharge hose to disperse the liquid as required. Remove any kinks from the hose to assure maximum water flow.
   Important
   Never point the hose at bystanders. 

4. Turn on the hydraulic power source. Watch for solids in the liquid being pumped. If solids are excessive, the discharge flow might decrease. If this happens, stop the pump and check for the cause of the problem.
   Under some conditions, the liquid being pumped might be slowed enough so It can no longer push particles in the liquid. If this happens, particles can accumulate in the hose and backup the pumping chamber, causing further restriction. The impeller then acts as a “grinding wheel which causes accelerated pump wear. Reduced liquid flow can be caused by the following:

   • The pump sinks into solids at the bottom of the hole.
   • The end of the outlet hose is too high, causing an excessive lift height for the column of liquid being pushed by the trash pump. This slows the flow of liquid to a level where it can no longer carry solids out the end of the hose.
   • The flow and pressure of hydraulic fluid to the pump is too low, which reduces impeller speed. A 20% decrease in hydraulic fluid flow can reduce pump performance by 50%. When operating at reduced hydraulic flow and pressure, the end of the outlet hose should not be more than 30 ft/9 m above the liquid.

5. When pumping is complete, set the hydraulic control valve to the “OFF” position. Lift the pump from the work area.

COLD WEATHER OPERATION

If the trash pump is to be used during cold weather, preheat the hydraulic fluid at low power source speed. When using the normally recommended fluids, fluid should be at or above 50 °F/10 °C (400 ssu/82 centistokes) before use.

Damage to the hydraulic system or pump motor seals can result from use with fluid that is too viscous or thick.

CLEANING THE PUMPING CHAMBER

Debris such as weeds, sand and other solids may become trapped in the water hose and pumping chamber. This can reduce pump performance. It is important that the pumping chamber be kept clean at all times. The chamber can be cleaned as follows:

1. Remove motor and impeller by removing the two M12 × 1.75 Hex Head capscrews.
2. Remove all debris from the pump screen.
3. Thoroughly clean the volute and impeller. Do not remove the impeller unless necessary for repair or replacement or to remove trapped debris.
4. Assemble the motor and impeller to the volute. Clean the cap screws and lubricate the threads with underwater grease before installation.
5. Remove all debris from the hose. Otherwise, solids will back fill the pump.

TOOL PROTECTION & CARE

Notice
In addition to the safety precautions found in this manual, observe the following for equipment protection and care.

• Make sure all couplers are wiped clean before connection.
• The hydraulic circuit control valve must be in the “OFF” position when coupling or uncoupling hydraulic tools. Failure to do so may result in damage to the quick couples and cause overheating of the hydraulic system.
• Always store the tool in a clean dry space, safe from damage or pilferage.
• Make sure the circuit PRESSURE hose (with male quick disconnect) is connected to the “IN” port. The circuit RETURN hose (with female quick disconnect) is connected to the opposite port. Do not reverse circuit flow. This can cause damage to internal seals.
• Always replace hoses, couplings and other parts with replacement parts recommended by STANLEY. Supply hoses must have a minimum working pressure rating of 2500 psi/172 bar.
• Do not exceed the rated flow. Rapid failure of the internal seals may result. See “SPECIFICATIONS” on page 14 for correct flow rate and model number.
• Always keep critical tool markings, such as warning stickers and tags, legible.
• Do not use the tool for applications it was not designed for.
• Tool repair should be performed by experienced personnel only.
• Make certain that the recommended relief valves are installed in the pressure side of the system.
• Do not use the tool for applications for which it was not intended.

TROUBLESHOOTING

If symptoms of poor performance develop, the following chart can be used as a guide to correct the problem.

When diagnosing faults in operation, always make sure the hydraulic power source is supplying the correct hydraulic flow and pressure as listed in the table. Use a flow meter know to be accurate. Check the flow with the hydraulic fluid temperature at least 80 °F/27 °C.

and check that 7–12 GPM/26–45 LPM at 1000-2000 psi/70–140 bar is available at the pump.
Defective couplers.| Check the couplers. Replace if necessary.
Impeller jammed with debris.| Clean the pumping chamber as described in the Maintenance section in this manual.
Impeller rubbing against wear plates.| Check and adjust the impeller clearance as described in the Service Manual.
Defective hydraulic motor.| Repair or replace motor.
Poor pump performance.| Hydraulic flow reversed.| Check that the hoses are correctly connected to the pump motor ports. The female coupler should be connected to the “IN” port. The return fluid must never flow through a reversing valve.
Improper hydraulic fluid flow.| Check that 7–12 GPM/26-45 LPM at 1000– 2000 psi/70–140 bar is available at the trash pump. A 20% decrease in flow can result in a 50% decrease in pump performance.
Pump submersed in sediment.| Lift the pump from the bottom of the hole or chamber. Use a flat support under the pump if necessary.
Trash pump inlet restricted.| Remove suction screen and thoroughly clean. Reassemble.
Discharge hose kinked or

restricted.

| Straighten the hose. If the hose must bend at the top of the hole, use a piece of split rigid conduit with large diameter of the expanded hose. This keeps the hose from kinking.
Discharge hose too small.| Use a 3-inch diameter fire hose.
Water lift too high.| Lower the outlet end of the discharge hose. Increase hydraulic flow (12 GPM/45 LPM max).
Impeller worn or damaged.| Check impeller for damage and excessive wear. Replace if necessary.
Pump not matched to application.| Obtain higher capacity pump.
Hose used on suction side of pump.| Remove. Use no plumbing on suction side of pump.
Poor pump performance with excessive wear.| Too many solids in the water. Water speed out of the hose may be too slow, therefore hose and pump load up with solids.| Reduce solids content. Increase pump speed.

UNDERWATER TOOLS DEPTH GUIDELINE

UNDERWATER MODELS ONLY

Caution
Do not use hydraulic tools underwater that are not designated as an “underwater” model, or this will result in damage to the tool.

For underwater hydraulic tools the applications are broken down into four quadrants depending on type of tool and method of operation.

The types of tools are percussive and rotational, each with different characteristics allowing for different depth operation. With percussive tools, the nitrogen accumulator PSI must counter the increase in ambient pressure found at lower depths. Since there is a maximum PSI for percussive tools they are limited to certain depths. Rotational tools do not have accumulators and thus are capable of deeper depths.

The methods are broken into diver operated or remote operated vehicle (ROV). ROV’s can reach lower depths and with an onboard hydraulic power source that is depth compensated, can operate hydraulic tools at depths of thousands of feet. ROV operation is still limited to the tool, for example a percussive tool has the same depth limitation whether ROV or diver operated.
