FAQs

How does a Miniverter Flexible Impeller Pump work?

This pump operates by the rotation of the internal shaft, which causes the flexible impeller to bend against the casing, pushing fluids and solids out of the discharge port.

What is the difference between a Centrifugal and a Flexible Impeller Pump?

A Centrifugal Pump is a Rotodynamic pump that passes energy from the motor to the liquid, which forces 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.

How does this differ from other products on the Tapflo website?

The Miniverter offers the same sizing and performance as the EP range, but with added versatility from a built-in potentiometer and reversing switch on the terminal box. This allows variable speed control (285–1400 rpm) and flow direction adjustment while remaining compact, portable, and simple to connect to a standard 230V single-phase supply

Can this pump run dry?

No, it can’t as it may cause damage to the motor, however, this pump is self-priming and the risk of dry runs is minimal.

Is this pump suitable for abrasive or hazardous chemicals?

Suitability depends on the specific fluid and material selection. With impellers available in NR, NBR, Neoprene, EPDM, and Silicone, and stainless steel pump heads in 316, the Miniverter can safely handle many chemical and wastewater fluids. For abrasive or highly hazardous chemicals, material compatibility should be reviewed case by case to ensure safe and durable operation.

Miniverter Flexible Impeller Pump

Tapflo UK is proud to be a partner of Liverani, a leading Italian manufacturer, supplying us with highest-quality Flexible Impeller Pumps and Liquid Ring Pumps.

The Miniverter Self-Priming Flexible Impeller Pump, is characterised by its close-coupled design and comprises 2 models, the MINI and MIDEX units. These units offer the same sizing and performance capabilities as the EP range, with the addition of a potentiometer for variable speed control. Self-priming up to 6m without the need for a non-return valve, and solids passage up to 5mm (MIDEX), these Flexible Impeller Pumps deliver pulsation-free flows and can be rotated and installed in various positions for enhanced versatility. With the Miniverter, operators can modify the speed range between 285 and 1400 RPM and can choose the direction of flow by using the integrated potentiometer and rocker switch located on the terminal box without compromising its standard IP55 protection rating.

Typical applications for our Miniverter Self-Priming Flexible Impeller Pumps:

  • Oenological
  • Brewery
  • Food & Food Oils
  • Chemical
  • Cosmetic
  • Pharmaceutical
  • Wastewater Treatment
Overview

The MINIVERTER MINI & MINIVERTER MIDEX offer the exact sizing and performance range as their EP counterparts; however, in addition to having an on / off / reversing switch on the terminal box, there is also a potentiometer which allows for variable speed control. Combined with their SS316 construction and various impeller & sealing materials, the result is the most versatile utility pump available today.

Speed range adjustment is from 285 – 1400 rpm, and optional manual and spring-loaded by-passes are available on request, along with U or L shaped Carrying Handles or Trolleys.

The feeding voltage is 230V/1 Ph/50 Hz which means that you have a portable pump which is capable of dry suction lifts up to 6 m, reversible. Variable flow, multiple pump head and mounting configurations, and solids handling are suitable for both thin and viscous liquids that can be plugged into a standard household plug socket. What could be easier!
