DESCRIPTIONThis manual contains installation, operation, assembly, disassembly and repair instructions for the

Fristam FLII 130 model rotary pump.

Fristam FLII Series bi-wing rotor pumps are positive-displacement pumps with non-contact rotors.

Non-contact rotation is achieved by the accurate positioning of the pump housing to the gearbox and

also by synchronous contra-rotation of the shafts running on very low-play rolling-contact bearings. The

pump assembly may be mounted to give the inlet/outlet ports horizontal or vertical configuration. These

ports are available with a variety of optional connections.

In the standard version, the FLII Series is available with a flexible coupling between the synchronous

gearbox and drive on a common baseplate.

On Fristam FLII Series rotary pumps, the line seal between the suction and pressure ports ensures that

the pump maintains its working capacity even after a long operating time. Due to high quality manufac-turing standards, close tolerances are consistently maintained. This results in tight tolerances between the

smooth working surfaces inside the pumping chamber.

DANGER: BEGIN ALL PUMP MAINTENANCE OPERATIONS BY DISCON-

NECTING THE ENERGY SOURCE TO THE PUMP. OBSERVE ALL

LOCK OUT/TAG OUT PROCEDURES AS OUTLINED BY ANSI Z244.1-

1982 AND OSHA 1910.147 TO PREVENT ACCIDENTAL START-UP

AND INJURY.!

UNPACKINGEQUIPMENTCheck the contents and all wrapping when unpacking the pump. Inspect the pump carefully for any

damage that may have occurred during shipping. Immediately report any damage to the carrier. Remove

the shaft guard and rotate the coupling by hand to make sure that the rotors rotate freely. Keep the

protective caps over the inlet and outlet in place until you are ready to install the pump. Do not rotate

with cover removed. Rotors, housing and cover could be damaged if shafts are rotated with

cover removed.

PIPING

Follow good piping practices to avoid stressing the pump housing. Support all piping resulting in zero

load on the pump housing. Piping should accommodate thermal expansion without stressing the pump.

SUCTION PIPING

Minimizing frictional loss in the suction piping will

improve pump performance. Locate the pump as

close as possible to the liquid source with a minimum

number of valves, elbows, etc.

If suction piping is larger than the pump inlet, use an

eccentric reducer, straight side up, to prevent air pockets

from forming (Figure 2) .

Figure 3

Avoid foreign matter from entering the pump. Size inlet traps and

strainer to protect the pump when necessary. To avoid cavitation,

implement operational procedures to clean suction strainers as required.

DISCHARGE PIPING

Do not operate FL II pumps with valves completely closed on the

discharge side. Damage can occur due to over-pressurization. Useintegral relief covers (available from Fristam Pumps, Inc.) or a recircula-

tion loop to prevent over-pressurization. Please

contact Fristam Pumps, Inc. for information on

proper operation of integral cover relief valves.

Install throttling valves in the discharge piping to control the pump

performance. Do not install throttling valves in the suction piping.

INSTALLATIONOFWATER FLUSHFORDOUBLEMECHANICALSEAL

Set up the water flush for the double mechanical seal (if installed) As shown inFigure 3. The seal flush

water should be supplied at a maximum flow rate of 12 gph(45.42 lph) at a pressure of 1-2psi (0.07 - 0.14 bar).

Note: maximum pressure = 5 psi (.35 bar). Exces-

sive flow/pressure through the seal flush

will cause excessive wear and shorten seal

life.

It is desirable to have the flush water on the

outlet side visible. This allows an easy check to

see that the flush water is on and also if the seal

is functioning properly. In a malfunctioning seal

the flush water will disappear, become discolored,or show an unusual increase in flow. If these condi-

tions exist, check the seal and replace if necessary.

ALIGNMENT

Provide sufficient room around the pump assembly for easy maintenance and inspection. Mount the

base plates on a solid foundation and double check the coupler alignment after installation. Refer to

Table 3, page 19, for the standard sure-flex coupling alignment requirements.

ELECTRICAL INSTALLATION

Fristam uses standard duty TEFC drives unless otherwise specified (for example, washdown, explo-sion-proof, etc).

Provide for adequate motor ventilation.

Ensure that the drive motor type is suitable for the environment where the pump is to be operated.

(Pumps intended for use in hazardous environments eg., explosive, corrosive, etc., must use a motor

with the appropriate enclosure characteristics. Failure to use an appropriate motor type may result in

serious damage and/or injury.)

Check pump for proper rotation.

prevent air pockets from forming.! WARNING

10/98

Note that a change in operating conditions (for example, higher viscosity, higher specific gravity, lower

head losses) may change the load requirements on the motor. If you have a question regarding the

power requirements for your application, please contact your local Fristam distributor or Fristam

Pumps, Inc. for technical assistance.

LUBRICATION

GEARSMaintain oil levels in the center of the oil sight glass located on the bearing housing. Change oil every

2000 hours under normal conditions or every 1000 hours under corrosive or dirty conditions. Use Citco

EP compound 220, Benz Oil compound 220 or equivalent.

BEARINGS

The front and rear bearings are sealed and lubricated for life.

START-UPINSTRUCTIONS

Remove any foreign matter in the pump or piping system before start-up. Do not use the pump to flush

the system!

Avoid abrupt closure of valves. This can cause hydraulic shock which may cause severe damage to the

pump and system.

Maximum discharge pressure at the pump should not exceed the values listed toward the front of this

manual.

MAINTENANCE

RECOMMENDED DAILYMAINTENANCE

Visually inspect and maintain the oil level at the halfway level in the sight glass.

Visually inspect the seals for leakage. Replace annually under normal operations; more often under

heavy operations.

PERIODIC MAINTENANCE

Note: through continuous use pump components may wear, therefore, setting up a preventive mainte-

nance schedule to detect wear before it results in damage to the pump is recommended.

Check for signs of wear on the shaft and rotor spline. Replace worn parts.

To replace the mechanical seal, the pump housing

(5) needs to be removed. Loosen the two housing

nuts (1) securing the pump housing to the gearbox

and remove. Slide the pump housing away from

the gearbox (17). If the housing is stuck, alter-

spacers (44) and the rotating seals (39) will come

off with the pump housing.

Clean and examine all of the pump components

for damage. Replace damaged components as

required. Fristam recommends replacing all of the

wetted elastomers during reassembly.

Pull the rotating seals (39) off the gapping

spacers (44) and remove both .

Place the pump housing (5) face up on abench and rest it on the two housing studs (4).

Place your thumbs on the ID of the front

stationary seals (9) and push downward to

press the stationary seals out of the pump

Use feeler gauges to verify the back and radial clearances between the rotors and the housing. A depth

gauge should be used to verify the front clearance. (see Table 2, page 16) Note: when checking

clearances the housing must be bolted at front using spacers and nuts.

BACKFACECLEARANCE

The rotor to housing back face clearance is maintained by the gapping spacer (44).

To check the back clearance mount the pump housing (5) onto the gearbox (17) less the seals. As-semble the gapping spacer (44), rotor (6) and rotor nut (45) onto the shaft. (Refer to Table 1, for the

proper rotor nut torque.) Measure the clearance between the back face of the pump housing and the

back of the rotor with a feeler gauge. Check the reading with the recommended back face clearance,

Table 2.

TOO MUCH CLEARANCE

If the clearance is greater than the clearance specified in Table 2, remove the gapping spacer (44).

Machine and lap the o-ring end of the gapping spacer to the required length. Lap the gapping spacer

until the shim faces are perfectly flat and the spacer thickness is the same around the entire circumfer-

ence of the shim. (Lap compound Liquid Diamond 14 microns.)

Re-assemble the gapping spacer (44), rotor (6) and rotor nut (45). Recheck the back face clearance.

Assemble the pump wet end up as outlined in the Pump End Assembly section (starting on page 15).

NOTENOUGHCLEARANCE

If the back clearance is less than the clearance specified in Table 2 a longer shim must be added.

Remove the gapping spacer (44). Install a standard length gapping spacer. Follow the procedures

outlined in the Too Much Clearance section above.
