MSSTM Series


Theory and Operation

Technical Description

Multi-stage seawater (MSS) pumps are centrifugal feed pumps specifically designed for seawater reverse osmosis (SWRO) service. MSS pumps develop pressure by using a series of impellers mounted on a rotating shaft. Rotating this fluid through centrifugal force develops a pressure higher than the input pressure. Pres-sure can be increased through the addition of impeller stages or by increasing shaft rpm. Motors are selected according to equipment

operating requirements. A flexible coupling al-lows the pump shaft to float within the coupling eliminating thrust against the motor. The inlet and discharge housing is designed to connect to grooved rigid piping with couplings. The inlet housing itself can be attached to the pump in four different positions 90° apart. A precision leveling foot supports the end shell housing and is fully adjustable to allow accurate pump to motor shaft alignment.

Theory and Operation Continued

MSS Pump Internal Components

The internal components of an MSS pump can vary depending on pump configuration and number of stages. The basic components contained in a single stage consist of an impeller and a diffuser with a spacer and bushing which prevent friction and wear.

Behind the discharge housing at the end of the pump is the WATER BEARING™ assembly. The balance disc rides in the bearing carrier and serves as a thrust bearing for the pump. This unique design uses patented WATER BEARING™ technology which allows feed water to cool and lubri-cate the balance disc. As the motor rotates the pump, pressure differences acting on the rotating impellers generate an axial thrust acting toward the motor. The water bearing employs the bal-ance disc to create a counter-pressure which exactly cancels the impeller thrust load. The bear-ing drain line and throttle nipple are used help produce the counter-pressure on the balance disc. This thrust and counter-thrust allows the disc to “self-balance” based on operating conditions.

Optional Baseplate InstallationSome units include an optional FEDCO baseplate which provides good mounting surfaces for the motor and pump. It also increases accuracy during the alignment process. Although the base-plate is precisely manufactured, it requires a solid foundation such as a concrete pad or rigid steel substructure. If the optional baseplate is used, it must be installed first to avoid distortion which may occur due to uneven floors or substructure. If the pump is installed within a container, it must be mounted on a rigid steel substructure that will not distort under the weight of the equip-ment or from torque reaction forces during pump operation.

Optional High Pressure Seal CarrierIf equipped with an optional high pressure seal carrier, a vent line from the HPSC should be vented to the atmosphere and positioned to drain normally or connected to a low pressure mani-fold behind the first high pressure pump in the train.

WARNINGUnder no circumstances should the vent line be plugged. A plugged vent line will result in insuf-ficient water lubrication of the seal and balance disc causing internal damage to the unit.

Optional Shaft Position SensorThe purpose of the shaft position sensor is to identify potential pump wear or failure before seri-ous damage can occur. The shaft position sensor is positioned directly above the position collar. If for any reason the shaft moves toward the motor, the collar moves out of range of the sensor shutting down the pump.

Recommended Instrumentation and OperationFor safe pump operation, a pressure switch or relief valve is recommended for the high pressure side (before the membranes). Pressure gauges should be installed at the inlet and outlet of the MSS pump. If a throttle valve is used, an additional gauge is needed on the output side of the valve. It is recommended that a pressure switch should be installed at the pump inlet to prevent pump operation if the feed pressure to the pump is below specifications. MSS pumps are not equipped with a check valve to prevent back flow. Refer to the pump yellow tag and pump nameplate for equipment specifications.

Upstream Filtration• The pump must be protected from debris in

the feed water such as sand, gravel, or other particulate matter.

• A 20 micron filter must be installed upstream of the pump inlet to protect against foreign matter entering the system.

• Temporary strainers should be installed before initial start up or after repairs to protect the pump from possible debris.

Preparation For Pump Start UpStart Up Precautions

WARNINGNEVER operate the pump equipment:• below the minimum flow rate.• when dry.• without priming.• without proper guards and safety devices

installed.• with the discharge valve closed.• with the suction valve closed.

ELECTRICAL HAZARDRefer to the motor name plate, electrical junc-tion box cover, or wiring tag for proper wiring. All electrical connections should be made by a licensed electrician according to all local codes and regulations. Be sure to follow all manufac-turer’s instructions on motor lubrication. Ensure motor rotational direction is correct according to the arrow located on the motor adapter (Refer to Motor Rotational Direction Check).

CAUTIONElectric motors may develop continual noise over long periods. Proper ear protection should be worn during pump operation. Most noise will emanate from the electric motor. The noise level of the MSS pump is nominal and depends on its size and operating conditions. The typicallevel can range from 75dB to 85dB, measured at a distance of 1 meter (39 inches) around the pump. Sound may vary due to hydraulic reso-nance, valves and building walls. For applications were a minimum noise level is required, the sys-tem should be operated with the flow adjusted as close to optimum efficiency as possible. Vibration may also occur and varies based on pump size and operating conditions. As a reference, typical

vibration levels can reach .177” (4.5mm) per sec-ond RMS. See vibration test records or specifica-tions sheet for more information.

Start Up Check ListAn additional start up check list is available in the rear of this manual. Also use the Start Up Record at the rear of this manual to record initial operat-ing conditions at pump start up. □ Flexible coupling set screws tightened. □ Motor adapter guards installed. □ All anchor bolts tightened to specifications. □ All pipe couplings tightened to specifications. □ Motor rotational direction correct. □ Motor lubricated to manufacturers

specifications. □ Final Pump Alignment performed. □ Inlet pressure indicator installed. □ Inlet pressure switch (if applicable) installed. □ Outlet pressure indicator installed. □ System pipes are clean and upstream filtration in place. □ System leak checked and all air vented from system. □ ALL safety devices in place.

Pump Start UpNOTES: Use the Start Up Record located in the rear of this manual to record initial operating con-ditions at pump start up.

1. Start pump and vent air from the system.2. Verify that there are no leaks in the system.3. Activate the MSS pump.4. Inspect the system for leaks.

NOTES: Some mechanical seal leakage may occur for about 60 seconds after pump start-up. If the leakage continues longer than 60 seconds then proceed with the Mechanical Seal Replace-ment procedure located in the MSS Overhaul Manual.

5. Observe any unusual system noise or vibra-tion.

6. If a vibration meter is available, record a base-line vibration reading at this time. Note this vibration level in the Start-Up Records section of this manual.

7. Adjust system valves and controls as needed to obtain the desired operating condition.

Basic Troubleshooting

If the MSS pump does not operate properly, refer to the following troubleshooting charts as a guide to determining the concern and identifying the potential cause. If after consulting the trouble-shooting charts the cause is still undefined, contact FEDCO technical support www.fedco-usa.com and choose the “Service and Support” tab, telephone or fax. FEDCO will give you easy, step by step instructions on how to proceed.

Visual Inspection• Make sure all items are accounted for on the start up check list.• Inspect all piping and electrical connections to the motor and pump.• Inspect the pump and motor mountings for signs of any movement or vibration.• Inspect pressure gauges, switches and all other instrumentation for proper operation.• Record any unusual readings.
