4.11  Oil Capacity 

The standard 680 metering pump requires approximately one quart of PULSAlube oil to fill both chambers and 

prime hydraulic pump head. PULSAlube oil is available in one quart bottles, one gallon bottles, 5 gallon pails or 

55 gallon drums.  

 

 

5.  Storage Instructions  

5.1  Short Term 

Storage of PULSA Series pumps for up to 12 months after shipment is considered short term. Under this 

condition the recommended storage procedures are as follows:  

 

1.

 

The pump should be stored indoors at room temperature in a dry environment. 

2.

 

The pump gearbox and hydraulic reservoir is to be completely filled with PULSAlube oil within two months 

after date of shipment. 

3.

 

The gearbox and hydraulic reservoir should be inspected ever 3-6 months. Maintain the oil level and assure 

that no water or condensation is present, follow Procedure II, Step A below. 

4.

 

It is recommended that the stroke length of the pump be adjusted to its midpoint and that the piston be 

manually cycled through 3-6 cycles every six months. 

5.

 

Prior to start-up, perform a complete inspection and then start up in accordance with instructions in this 

manual. 

 

5.2  Long Term 

For storage longer than 12 months in addition to the above, the following procedures should be followed. 

 

1.

 

Every 12 months PULSAlube oil should be drained from the gearbox and hydraulic reservoir. The gearbox 

and the hydraulic reservoir should be flushed with kerosene or petroleum base solvent, thoroughly dried out 

with a rag, and then refilled with fresh PULSAlube oil. 

2.

 

Every 12 months the motor should be connected to a power source and the pump operated for a minimum of 

one hour. It is not necessary to have liquid in the reagent head during this operation but the suction and 

discharge ports must be open to the atmosphere. 

 

After 12 months storage, Pulsafeeder’s warranty cannot cover such items as oil seals, gaskets, piston cups, and 

other items which are subject to deterioration with age. If the pump has been in storage for longer than 12 months, 

it is recommended that these items be replaced prior to going into service. Material and labor to recondition or 

replace this class of item is the purchaser’s responsibility. For a one year service warranty after extended storage, 

the refurbishment and equipment inspection must be done by a Pulsafeeder serviceman.
