Our Inverter Drive Self-Priming Flexible Impeller Pump has been designed as a simplified alternative to the INV Series. This model excels at transferring sensitive, delicate fluids, including viscous substances and suspended solids up to 25mm. It features 3 close-coupled pumps, fitted with ventilated motors on a trolley system.
Due to the 4 kW inverter drive system, the feeding supply for both models needs to be 400V three-phase.
Typical applications include:
| Max Capacity (m³/hr) | 22.5m³/hr |
| Max Pressure (m) | 32m |
| Max Temperature (°C) | 100°C |
| Max Viscosity (cP) | Up to 50,000 cP |
| Outlet Sizes | 1″ BSP F to 2½” RJT |

What a Flexible Impeller Pump is, how it works, and how it can be used for your sector.
A mobile pump solution to fill and empty tanks for non-alcoholic botanical drinks.
This pump operates by rotating the internal shaft, which causes the flexible impeller to bend against the casing, pushing fluids and solids out of the discharge port.
A Centrifugal Pump is a Rotodynamic pump that transmits energy from the motor to the liquid, thereby forcing the fluid out of the discharge port.
The Impeller Pump is a Positive Displacement Pump that traps small amounts of liquid and forces it from the suction to the discharge port.
The INV-BS series is a cost-effective alternative to the INV range. It features simplified controls with speed adjustment from 175 to 1400 rpm, a reversing switch for bi-directional flow, and a compact 2-wheel trolley design. Unlike the INV series, it does not include dry-run protection.
Yes, they can self-prime up to 6m suction lift from dry.
No. Running dry can damage the impeller or mechanical seal. Unlike the INV series, the INV-BS range does not include dry-run protection, so the pump must always be operated with liquid present.
Suitability depends on the application and material selection. With impellers available in NR, NBR, Neoprene, EPDM, and Silicone, and pump heads in 304L or 316L stainless steel, the INV-BS can handle a wide range of fluids, including some chemical and cosmetic products.
For highly abrasive or aggressive hazardous chemicals, material compatibility should be checked on a case-by-case basis to ensure safe and reliable operation.
