Can the PV7 pump be installed vertically (inverted)?
No, horizontal mounting is recommended (shaft extension horizontal or upward) to avoid poor internal lubriion and bearing overheating.
What is the maximum allowable suction height for the PV7 pump?
≤0.5m (distance from tank liquid level to pump suction port); increase pipe diameter or add an auxiliary suction pump if exceeded.
What type of coupling should be used for PV7 pump installation?
Flexible couplings (e.g., plum-blossom or jaw-type) are mandatory; rigid couplings are prohibited.
What is the required coaxiality between the PV7 pump and motor?
Coaxiality ≤0.05mm; check with a dial indior to prevent shaft bending and bearing damage.
How to torque the mounting bolts of the PV7 pump?
Use 8.8-grade high-strength bolts and tighten them evenly in a diagonal pattern (e.g., M8 bolts: 12-15N*m; M10 bolts: 25-30N*m).
