VARISCO PS Drive series

Application areas & service documents

Frequency converter


Energy saving through motor speed control.
– Smooth starting and stopping.
– Extension of the operating time of the pump and protection against overload.
– Can be installed in damp environments thanks to the IP55 protection rating.
– Simplified installation on the motor or on the wall.
– Fast commissioning thanks to guided initial configuration.
– High thermal and mechanical performance thanks to the all-aluminum tank and independent ventilation.
– Guaranteed flexibility by using the same pump model for different flow rates and heads (fewer pumps and spare parts in stock, versatility for minor changes to the system or performance requirements).
– Ideal for on-site adjustments without the use of valves or bypass systems (significant energy savings).
– Possibility of setting the operating parameters using signals from external sensors such as level, pressure and pump capacity.
– The VARISCO PSDrive app enables Bluetooth® SMART communication with all PSDrive devices.
