Connections can be made to the pump either directly or using the range of adaptors supplied
in the optional test kit.
2.2.1 Direct
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. Fit a suitable blanking plug to an
unused port.
NPT ports can be fitted with any suitable length ¼ NPT male connector. Fit a suitable blanking
plug to an unused port. 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.
2.2.2 Swivel Adaptors (optional)
The single, ¼ BSP, swivel adaptor connects with a range of fixed adaptors. Using the knurled
grip-feature, hand-tighten (clockwise) the swivel adaptor, until it is fully inserted.
2.2.3 Swivel Pump Head
The pump head swivels through 140° providing optimum viewing angle and bench-top
operation. Placing the pump on the bench allows greater force to be applied to the scissor-
action handles. Internal stops prevent further rotation of the pump head.
Note: Do not use excessive force when rotating the pump head.
