2.2 Handling
Boxes, crates, pallets, or cartons may be unloaded using forklift vehicles or slings dependent on
their size and construction. Slings, ropes, and other lifting gear should be positioned where they
cannot slip and where a balanced lift is obtained. If lifting without equipment, follow safe practices
to avoid injury (i.e. lifting with two people).

Storage Instructions
3.1 Short Term
Storage of PulsaPro pumps for up to twelve (12) months is considered short-term. The
recommended short-term storage procedures are:
o
Store the pump indoors at room temperature in a dry environment
o
Confirm or fill the eccentric box to its normal operating level with PULSAlube 6H-GS
hydraulic oil. If required by the operating environment, take steps to prevent entry of water
or humid air into the eccentric enclosure.
o
Prior to startup, inspect the housing and gearbox. Replenish hydraulic oil as required to
maintain operating levels. If water or condensation is present, change oil as described
under Equipment Set-Up.
o
Start up in accordance with instructions in this manual
3.2 Long Term
Every twelve months, in addition to the above short-term procedures, power up the motor and
operate the pump 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 atmosphere. If the pump
is equipped with a PULSAlarm vacuum leak detection system, ensure that a vacuum is drawn
before operating the pump. See Appendix I for more information.
After twelve months of storage, Pulsafeeder Warranty cannot cover such items which are subject to
deterioration with age such as seals and gaskets. If the pump has been in storage longer than
twelve (12) months, it is recommended that such items be inspected and replaced as necessary
prior to startup. Materials and labor to replace this class of items under these circumstances are the
purchaser’s responsibility. For continuance of the warranty after extended storage, equipment
inspection and any required refurbishing must be done by a Pulsafeeder Representative.

Principles of Operation
4.1 Overall Operation
A piston reciprocates within an accurately sized cylinder at a preset stroke length, displacing an
exact volume of fluid. The piston, however, does not pump various chemicals. The piston and
associated mechanisms are enclosed in a gearbox that also serves as a hydraulic oil reservoir. A
diaphragm separates the oil from the product pumped. The diaphragm moves in exact response to
piston displacement. The diaphragm does no work and acts only as a separator. Consequently,
the oil displacement is translated into equal product displacement. The piston retraction causes the
product to enter through the suction check valve. Piston advancement causes the discharge of an
equal amount of product through the discharge check valve.
Individual pumps may vary in appearance due to various liquid ends, accessories, and multiplexing.
The basic principles of operation, however, remain the same.
