VA & INV Flexible Impeller Pumps

Our VA Series is characterised by its ability to adjust its speed by its integral mechanical variator, which changes the mechanical output speed of the gearbox. Flow control isn’t as accurate as the INV series. However, it provides a decent flow range for applications where precise flow control isn’t necessarily required. Speed adjustment must be done whilst the pump is at a standstill, not during operation.

All VA series units are 3 phases as standard.

Our INV Series provides the widest and most accurate flow control as you can infinitely vary the speed of the motor between its min and max speed points by using 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.

The feeding supply for the INV series can be either 230V single phase (up to 2.2 kW) or 230-400V three-phase.

• Variable Speed Adjustment: The VA series features an integral mechanical variator that allows for adjustable speed while the INV series features a pre-wired and calibrated inverter panel for precise speed control
• Flow Control: VA series is suitable for applications that don’t require exact flow control, while the INV series offers the widest and most accurate flow control range
• Operational Safety: Speed adjustment is possible only at a standstill with the VA series, while dry-run protection is included in the INV series
• Configuration: Standard 3-phase configuration for the VA series and single or 3-phase supply options for the INV series
• Enhanced Performance: Increased flow and pressure options available on all MAXI models
• Additional Features: Optional manual or spring-loaded bypasses on both series, while the INV series can be trolley-mounted with CE Control Panel and remote control included
