1. GENERAL DESCRIPTION The pump is a single stage vertical centrifugal type, driven by a built-in hydraulic motor. The sealing arrangement consists of a mechanical seal against hydr. motor, and two single lip seals against cargo. The pump is available in two versions: - Concentric hydraulic hoses with the outer return house in acid resistant material, for use

on solvent products. - Separate pressure and return hoses for use on oil products. Sectional drawing with identification of main parts - see fig. 1 and fig. 2.

3. OPERATION INSTRUCTIONS The speed control valve on the starter head must be closed. Connect return hose to snap-on coupling station on main return line, secure it by turning the

retaining ring. If necessary, and to minimize the connecting force, open the check valve bleed plug to relieve any trapped hydraulic oil between the check valve and the snap-on coupling.

Check that the ball valve on pressure snap-on coupling station is closed before the pressure hose is connected.

Secure the coupling by turning the retaining ring, and then open the ball valve. Note! Always connect the return hose before connecting the pressure hose. Start the pump slowly and run it on deck for about 30 seconds. Flush the impeller suction

area with fresh water. Watch for hydraulic oil leakage or other signs of improper operation (abnormal noise etc.).

Lower the pump into the cargo using a sling and portable winch. Note! The flexible hoses must not be used for hoisting or lowering purposes. O Stopp C C R N

Note! The hydraulic snap-on couplings on the pressure hoses are different from those on the return hoses. These couplings must not be interchanged, making it possible to connect the pressure line to the return chamber of the pump. In this case the pump will burst. pen the speed control valve on the starter head slowly until required capacity is obtained.

ing the pump: losing the speed control valve stops the pump.

lose the ball valve on pressure snap-on coupling station. elieve the pressure in the hose by opening speed control valve a short period of time.

ote! Always close pressure line valve and disconnect pressure hose before return hose.

ing: or cleaning the pump and hoses outside, use steam or flush with fresh water, according to

ype of cargo discharged. or cleaning the pump inside, run the pump in fresh water in a drum on deck or use steam. If team is used for cleaning the pump, the steaming out period should be as short as possible o avoid damage on seals or hydraulic motor.

nnecting from hydraulic ring line: isconnect the pressure snap-on coupling first. rain of approx. one cup hydraulic oil from the pressure hose. heck that the snap on coupling is clean and corrosion protected (greased).

nstall dust cap. isconnect the return side snap-on coupling the same way.

All parts to be stored in dry areas. 4. SERVICE INTERVALS, TESTING OF PORTABLE PUMP. Sealing arrangement: The arrangement consists of three shaft seals. One mechanical seal against hydraulic oil, and two single lip seals against cargo. Provided that the hydraulic system is kept clean, the mechanical seal will have a long service life. The lip seals service life will depend on the amount of sediments in the cargo, and operational speed of the pump. The static o-rings may cause leakage if faulty inserted or defect prior to installation. Because of above, the o-rings must be thoroughly checked prior to installation and care must be taken during assembling to obtain proper installation of the seals. Impeller: The impeller does not have to be replaced unless severely corroded / eroded. The impeller needs replacement if the seal surfaces are corroded. Hydraulic motor: The hydraulic motor has a long lifetime and does usually not require service. Generally, the noise level will increase if the motor is worn-out or damaged and need replacement. FRANK MOHN SERVICE personnel should carry out replacement. Testing of the portable pump:

Once a year we recommend to run a function, capacity and drill test of the portable pump. Framo suggest the following procedure:

Hook-up the unit to the main system as standard routine. Hoist the portable pump into the sea (the sip is not sailing) or into an available cargo

tank with water. Run the pump with full speed (control that the locking screw on the starting head is

in a correct secured position to prevent the hand wheel from turning off). Never start the pump if this locking screw is missing!

Run the pump for approx. half an hour and control the hydraulic pressure and the pump capacity.

Make a visual control of the complete unit. Then run the pump with reduced speed in a drum with fresh water on deck for

flushing and control for any hydraulic oil leakage.

Note! After use, always remove the plug to the leakage chamber on pump head and check for leakage of either hydraulic oil or cargo. If any cargo leakage, replace cargo seals before further use. A small amount of hydraulic oil is normal.

5. TROUBLE SHOOTING

SYMPTOM

POSSIBLE REASON

REMEDY

The portable cargo pump will not start although pressure gauge indicates system pressure.

Impeller stuck.

Check the impeller.

The pump is vibrating heavily during discharging.

Impurities stuck in the impeller. Worn-out hydr. motor.

Check the impeller. Contact FM Services AS for replacement of hydr. motor.

Too low capacity.

A rag (cloth) in the impeller.

Check the impeller.

Hydraulic oil in Leakage Chamber.

Worn-out mech. oil seal. Leaking o-ring joints.

Replace mech. oil seal. Check o-ring grooves andinstall new o-rings.

Cargo in Leakage Chamber.

Worn out cargo seals. Worn out impeller - Seal surface damaged.

Replace cargo seals. Replace impeller.

6. SERVICE Replacement of wear ring: - Use a seeger-ring pliers for removal of lock-ring. - Do not bend the lock-ring beyond its yield-point.

1150-0021-4 22Jun00/JBE 11 of 18

Replacement of shaft seals:

- Remove suction cover and impeller. - Unscrew 4 bolts and remove lock ring. - Remove lip seals. A suitable pliers or others may be required to remove spacer ring and upper lip seal. - Remove cofferdam plug. Blow with air into cofferdam to ensure no restriction on openings into seal house. - Before assembly of new seals, clean seal house thoroughly. - Before assembly of impeller, install tool 0259-0492-4 on motor shaft, and leave it on for 5 minutes. Then remove the tool, and install impeller immediately.

Replacement of mechanical seal:

- Remove suction cover and impeller. - Remove lock ring, and pull out the seal housing. - Remove the lip seals from the seal house. - Use tool 0162-0755-4 to remove stationary seat (Fig.6) - For replacement of rotating seat of mechanical seal, the motor kit must be pulled out of the housing. - Before assembly of seal house, install guiding tool 0259-0492-4 on motor shaft.

FRANK MOHN SERVICE PERSONELL SHOULD CARRY OUT ANY FURTHER DISMANTLING.

DISMANTLING/ASSEMBLING Dismantling is done in reverse order of assembling. Refer fig. 9a and fig. 9b.

Pay special attention to the following: - The control plate is not fixed to the intermediate flange/hydraulic adapter, and may fall off. - When replacing hydraulic motor, new shims between hydraulic motor and seal housing may be required. Use tool 259-377-3 and a feeler gauge to select correct shim thickness. - The stud bolt in the shaft should not be dismantled if not loose or damaged. - The lock screws on the rotating part of the mechanical seal must be tightened equally, when mounted on to the shaft.

CLEANING OF PARTS DISMANTLED All parts must be thoroughly cleaned and examined. All parts where loctite has been, and will be used during assembling, must be thoroughly cleaned for dirt and old loctite. The lapped faces of the mechanical seal should be cleaned using clean rags in combination with denatured alcohol. The sliding surface of the control plate and the rotary group on the hydraulic motor, must be checked for any sign of mechanical wear. Any sign of abnormal mechanical wear or damage on any parts, must lead to immediate replacement. USE ONLY GENUINE SPARE PARTS.
