FAQ:
1. What is the required flatness of the PV7 pump mounting surface?
The flatness should be ≤0.1mm/m; use a straightedge and feeler gauge for inspection.
2. Can the PV7 pump be installed vertically (inverted)?
No, horizontal mounting is recommended (shaft extension horizontal or upward) to avoid poor internal lubrication and bearing overheating.
3. 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.
4. 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.
5. What is the required coaxiality between the PV7 pump and motor?
Coaxiality ≤0.05mm; check with a dial indicator to prevent shaft bending and bearing damage.
