Wherever possible, use o-ring seals in the connection ports,
this is the recommended method of sealing.
Fluid Reservoir (Figure 2)
The main body of the reservoir is transparent acrylic providing a
clear view of the contents.
The reservoir can be removed from the pump without the need to
empty the fluid, a self-sealing connection prevents leakage. The
spring-loaded top cover seals under atmospheric pressure
conditions, but vents excess internal pressure harmlessly in the
event of inadvertent pressurization.
The reservoir, connects to the inlet port on the top of the pump and
supplies fluid to the pump system for pressure generation.
In vacuum mode, used in priming, the fluid flow is reversed, fluid is
drawn from the two outlet ports and through to the inlet port and
the reservoir.
