Installation/Piping/Wiring
NOTE
Do not hold the pump head to lift the pump unit up, or the pump head may deform and a leak may result.
Installation
Observe the following points during installation.
● Installation location
Mount the pump indoors. Allow sufficient space around the pump for easy access and maintenance.
● Mounting position
• Install the pump as close to a supply tank as possible in a flooded suction system.
• Make sure the discharge-line end-nozzle is positioned higher than a chemical liquid level.
● Mounting direction
Always mount the pump with the outlet upward and the check valves upright. Otherwise, performance may
be reduced.
● Anchoring
Fix the pump with four M4 mounting screws (with PW and SW).
Piping
Observe the following points during pipework.
● Pipe connection
Both inlet and outlet of the pump are provided with Flowell tube fittings. Secure every joint properly to elimi-
nate any possibility of air ingress, or performance may be reduced.
● Fitting and Tube
Take account of corrosion and pressure resistance when selecting fittings and tubes.
● Pipe resistance
Keep a piping length shortest with the minimum number of bends.
