The Mechanical Speed Variation and Inverter Drive Flexible Impeller pumps are identifiable by their mechanical speed variation, which adjusts the output speed of the gearbox. The series is also characterized by their dry run protection and come supplied with a trolley and inverter control panel
This series is made up of the VA and INV. The VA pump provides a flow range that is ideal for applications that don’t require accurate flow control. The INV Series has a much more accurate flow control. This is achieved through an affixed inverter panel that is pre-wired and calibrated to ensure the speed of the motor is between the minimum and maximum speed points.
Speed adjustments to the VA & INV Series cannot be adjusted whilst the pump is in operation.
VA Self-Priming Flexible Impeller Pumps
The VA Series is characterised by its ability to have its speed adjusted by means of its integral mechanical variator, which adjusts the mechanical output speed of the gearbox. Flow control isn’t as accurate as the INV series, however, provides a decent flow range for applications where accurate flow control isn’t necessarily required. Speed adjustment must be done whilst the pump is at standstill, not during operation.
All VA series units are 3 phase as standard.
INV Self-Priming Flexible Impeller Pump Series
The INV Series provides the widest and most accurate control of flow as you can infinitely vary the speed of the motor between its min and max speed points by use of the pre-wired and calibrated inverter panel. As with the RID series, the INV MAXI DOUBLE 2Q doubles the flow of the INV MAXI 80 & INV MAXI DOUBLE 2H doubles the head.
As standard, the INV Series is supplied trolley mounted and with a CE Control Panel with an integral inverter, remote control on a 15 m cable with on/off/reverse & Speed Adjustment, dry-run protection & supplementary 24V NC Contactor for wiring to any additional fluid accessories such as Flow Meters, Pressure Switches or Transducers etc.
Feeding supply for the INV series can be either 230V single phase (up to 2.2 kW) or 230-400V three-phase.
