Durable Lobe Pumps Conveying Chemically Aggressive Fluids With Safe Valve

Accuvon rotary lobe pumps

Accuvon rotary lobe pumps convey different fluids, whether with low or high viscosity, containing solids or pure, chemically aggressive or up to a temperature of 200°C. Due to the large selection of different materials, rotors and sealing systems, the pumps can be customized.

Our pumps are available in the series of 4 series with 16 different sizes andflow rates of 1 to 3200 m³/h – high performance with smallest footprint.

Operating Principle

Rotary lobe pumps are not sensitive to dry running and are self-priming positive displacement pumps. The synchronized rotation of the rotor pair and the increasing suction chamber

create a vacuum on the priming side of the pump. This vacuum draws the liquid into the pump chamber. The pumped medium is conveyed past the pump wall into the pressure area by the

rotors. The synchronized rotation of the rotor pair and the decreasing pressure chamber create an over pressure on the discharge side of the pump. The flow direction can easily be reversed by changing the direction of rotation.

Unrivaled Low Maintenance

Due to the cantilevered carrier design of the pump, the wear parts stressed by the pumped media can be replaced through the quick-release cover of the pump. All maintenance work can be done without the need to remove piping and the drive system.

Outstanding Range Of Material

The correct selection of material is important for the durability of a pump. For this reason, all components of our pumps are available in different materials. Using a modular principle, the most resistant material most suitable for the relevant pumped medium is selected for each pump component, from the O-ring to the pump casing.

Unique Block Design

Each rotary lobe pump is equipped with a non-segmented pump and gear casing. This design reflects our high quality standard and guarantees long service life with ease of maintenance. The pump casing can be manufactured in cast iron, cast steel, stainless steel, duplex steel or Hastelloy.

Variety Of Rotors

We offer a range of linear and screw rotors differentiated by geometry and material. Whether made of NBR, EPDM, FKM, stainless steel, steel or another material, we offer a suitable rotor for your application.

Seal Selection

Our single- or double-acting mechanical seals are available in different versions and materials. The seals can be replaced very easily through the quick-release cover.

Unique Casing Protection

In order to prevent pump casing damage, e.g. due to abrasive or aggressive fluids, Accuvon pumps are equipped with casing protection. The unique casing liners and casing protection plates are available in different materials.
