Frequently Asked Questions
What is the "zero stroke" condition?
This is the state where the pump regulates the flow to virtually zero while maintaining system pressure, minimizing energy loss and fluid heating.
What is the case drain flow at zero stroke?
For Frame Size 06, it's 1.7 L/min, and for Frame Size 20, it's 2.0-2.4 L/min, measured at maximum outlet operating pressure.
What are the control times for pressure regulation?
Control times vary by model and pressure setting. For example, a PV7../06-10 pump has a control-down time (t2 down) of around 90 ms and a control-up time (t2 up) of about 60 ms at 100 bar.
What is the weight of these pumps?
Frame Size 06 pumps weigh approximately 6.3 kg, while Frame Size 20 pumps weigh about 11.4 kg.
How do I interpret the PV7 ordering code?
The code specifies type, series, frame size, displacement, rotation direction, shaft type, connections, seals, control unit, and zero stroke pressure setting. For example, 'PV7-1X/06-10RA01MA0-05' decodes to a specific configuration.
