5.5. Fluıd lıne
5.5.1. Fluid suction line
1- Use a conductive hose or pipe.
2- Screw fluid fitting into the pump inlet
tightly.
3- If the inlet fluid pressure is more than
25% of the outlet working pressure, ball
check valves will not close fast enough,
result will be inefficient pump operation.
4- At inlet fluid pressures greater than 15
psi (0.1MPa, 1 bar), diaphragm life will be
shortened.
5.5.2. Fluid discharge line
1- Use a conductive fluid hose or pipe.
The pump fluid outlet is 1/4". (f).
2- Screw the fluid fitting into the pump
outlet securely.
3- Install a fluid drain valve at the pump
outlet.
4- Install a fluid shut off valve at the fluid
outlet.
CAUTION!
Do not over tighten fittings that are used for
connection to the pump. Overtightening may
damage the pump.
