OPERATION
1. Check oil level, add oil if necessary.
2. Make sure system fittings and connections are tight
and leak free.
3. Place control valve lever in the middle (Neutral/Hold)
position to prevent accidental lifting or moving of load.
4. To start the motor:
(a) For PE series, turn the ON/OFF switch on the
control box to ON position.
(b) For PEW series, press and hold on the switch of
the remote pendant.
5. Let the pump idle for a few minutes before put into
operation.
Note. To ensure smooth operation, bleed air from the
system by fully advancing and retracting the cylinder
several times.
6. Use the control valve lever to control the direction of
fluid flow. These pumps are equipped with a 4-way 3-
position valve. Refer to figure 3(a) on page 5 for the
flow path.
7. Always monitor the pressure, load and position.
8. Shift the control valve, until desired pressure, load or
position is read.
Note: Do not continue to operate pump after cylinder
plunger is fully extended or retracted.
9. To turn off the motor:
(a) For PE series, turn the ON/OFF switch on the
switch box to OFF position.
(b) For PEW series, the motor will stop when the
switch is released.
10.Depressurize all connections before disconnect.
Note: Control valves on these pumps are 4-way, 3-
position, for use with double acting cylinders. If your
application require a 3-way setting shown in figure 3(b),
it can be changed by an authorized BVA Service Center.
If you have any doubt, please consult BVA Technical
Service 888-332-6419.
BEFORE USE
Read all instructions carefully before attempting to
assemble or operate these pumps. Most malfunctions
in new equipment are the result of improper operation
and/or improper set-up assembly.
Visually inspect all components for shipping damage.
Do not use if any damage is found.
Note: E-Pumps are shipped without hydraulic oil filled.
Add oil before starting motor and operation.
Familiarize yourself with the specification and illustrations
in this owner manual. Use service parts drawing on page
8 thru 11 as reference of location and assembly.
Electrical Connections:
1. Compare motor nameplate against power availability
to prevent motor burnout or dangerous electrical
overloading.
2. (a) Model PE0501/PEW0501 (0.5hp), PE1002/
PEW1002 (1hp) and PE1503/PEW1503 (1.5hp)
motors are wired for 110 volts unless otherwise
specified, and are supplied with a plug and cord.
(b) Model PE3005 & PEW3005 (3hp) have accessible
motor leads and should be connected only by a
qualified electrician to prevent improper connection and
possible damage to the motor.
3.Try to minimize the use of long extension cord and
make sure the wire size is adequate and with grounded
connections.
Hydraulic Connections:
1. Make sure to use correct type of hydraulic oil specified
by the manufacturer. Check and make sure the oil
level in reservoir is at about 2" from top of reservoir
plate, with cylinders retracted and motor off.
2. Use of pressure gauge is strongly recommended.
Attach a pressure gauge between the pump and
cylinder to monitor pressure on cylinder.
3. Make sure coupler, hose, valve, gauge are tighten
securely to prevent accidental removal of components
while in use. Hoses shall not be kinked or twisted.
Note: Always secure threaded port connections with
non-hardening pipe thread compound. Take care not to
introduce compound into port orifices.
4. Do not exceed the rated capacity of the equipment
connected to the pump. Use larger capacity of
cylinders if necessary.
IMPORTANT: The pump's maximum working pressure
is 10,000 PSI. Make sure that all hydraulic equipment
such as cylinders, hoses, coupler and etc. used with
this pump are rated at 10,000 PSI operating pressure.
