Alfa Laval Rotary Lobe Displacement Pump GHPD-532

1. Pump supplied grease filled.

2. Change - every two years (dusty air conditions)

* Change - every six years (clean air conditions)

3. Fill with grease by pumping grease into the rear of the gearcase.;

1. The pump will NOT be supplied oil filled.

2. First change - After 150 hours of operation.

3. Fill with oil through the filler plug to the level indicated in the sight glass.;

1. Checking the oil level in the gearcase (if applicable).

2. Checking the mechanical seals for leakage and replacing as necessary.

3. Adjusting the packed glands to control leakage.

4. Checking the oil seals for leakage.

CAUTION! DRIP LEAKAGE IS ESSENTIAL TO PREVENT OVER HEATING OF THE GLAND AREA WHICH WILL CAUSE SEAL FAILURE.

IMPORTANT! Stop and remove gland guard for checking temperature of housing and observing leakage. ALWAYS REPLACE THE GUARD BEFORE RESTARTING.

1. Lightly tighten up the gland follower.

2. Flood the pumphead and determine if the gland leakage is acceptable. Tighten the gland follower nuts until an acceptable leakage is achieved.

3. Start the pump and allow to run for 10 minutes. If the gland becomes significantly hotter than other parts of the pump, the gland is too tight.

4. Stop the pump and allow it to cool then repeat the above until the gland temperature is stable and gland slightly weeping.

5. Run the pump at 10 minute intervals tightening the gland follower nuts by a ½ of a turn until the leak is at an acceptable rate.;

– The large 'O' ring sits within the rotorcase bore and runs on the shaft sleeve. Rotation for the shaft sleeve is provided by a spring which locates in a slot on the shaft. An 'O' ring seals the shaft sleeve to the shaft.

2. Slide the shaft sleeve from the shaft and inspect the 'O' rings.

1. Lightly lubricate the 'O' rings with greas (food quality if necessary), locate in the shat sleeve and rotorcase bore.

2. Slide the shaft sleeve onto the shaft an locate the pin into the slot on the shaft.;
