Priming aid
Priming aid
The priming aid is a transparent, air-tight collector with
a screw cap on top. It is mounted between the tank and
the pump. The inlet from the tank and the outlet to the
pump are both at the bottom of the collector.
The priming aid is supplied with a bracket for wall
mounting and a rod for mounting on top of the tank.
The priming aid has the following functions:
Priming.
The priming aid facilitates priming in case of fre-
quent stops and/or high suction lifts by eliminating
or reducing the dry-suction phase.
Gas trap.
Gas occurring in the suction tube is trapped in the
top of the priming aid to prevent it from entering the
dosing head.
Pulsation dampening.
The dampening gas cushion in the top of the prim-
ing aid reduces pressure surges, resulting in opti-
mum dosing accuracy and reduced risk of
cavitation.
Material: PVC.
