1. Introduction
The PV 212 is a portable source of hydraulic pressure.
Each pump includes a reservoir, and a volume control for
fine adjustment. To prevent damage to sensitive
instruments, there are five pressure relief valves available
for different pressure ranges.
2. Operation
WARNING
Before applying pressure, make
sure all connections are correct and
equipment is internally clean and free from
damage.
Make sure that all equipment is to the correct
pressure rating.
Do not exceed the maximum operating
pressure stated in the specification.
Observe the relevant health and safety
precautions.
CAUTION
If PTFE tape is used to seal NPT
threads, ensure that only a sufficient amount
is used to achieve pressure seal. If excess
tape is used, particles can become loose
during the connector mating process and
enter the pump, potentially leading to loss of
pump performance or pressure leaks.
Note: Wherever possible, use o-ring seals in the BSP
connection ports this is the recommended method of
sealing.

2.1 Connecting the Pump
BSP ports can be fitted with any suitable length ¼ BSP
male connector, sealing either with an o-ring at the bottom
of the port or a bonded seal at the top. Adaptors are
supplied to convert the BSP ports to ¼ NPT. Fit a suitable
blanking plug to an unused port.
