BNM - MAINTAIN-IN-PLACE PUMP

With gauge connection. Flange connections alternatively to DIN or ANSI.

Wear resistant and corrosion-proof materials.

With short pitches and a compact design, the conventional geometry produces high pressures.

With a small rotor diameter and a long pitch, the 6L geometry attains lower surface velocities and extends the service life due to its large sealing line.

The rotor with Tricam geometry features a three-helix geometry. This enables it to achieve larger conveying capacities with the same overall length of the pump.

The seal on both ends is moulded as an integral part of the elastomeric stator; corrosion of the stator tube is never a problem because the pumped liquid never comes into contact with the metal tube or the bonding adhesive. Available with optional adjustable stator retensioning device.

Sliding separate casing with enlarged cross section ensures quick and easy maintenance.

Allows to separate rotor without dismantling joints. Axial space for dismantling rotor/stator without removing pipes.

Simplifies the handling of the casing element.

Holds suction casing in position when lantern is removed.

Quick and easy access to the drive sided joint.

Can be removed from the rear of the suction casing to maintain the drive sided wear parts

Geared motors, variable speed drives or frequency controlled motors of all major manufacturers, directly flanged to the pump without additional couplings or guards. Covers made of stainless steel are available.

The pressure gauge switches off the pump as soon as a pre-set pressure is exceeded or not reached and protects the pump from increased wear and tear or piping damage.

TSE monitors the temperature of the rotating stator and shuts down the pump when the limit value is reached to protect the pump from dry running.

This unit protects the shaft sealing by selectively supplying barrier liquid. Also available with flow meter on request.

Particularly robust design with integrated drip tray; base plate for applications in the oil and gas industry.

Universal seal for hopper and standard pumps for sealing the plug-in shaft and suction casing or feed hopper. Also available with grease or lantern ring to shut off the media flow. Can also be supplied with upstream labyrinth seal and additional flush connection or lubricating device.

Universal standard mechanical seal for dosing, food applications and semi-submersible pumps for sealing the plug-in shaft in the suction casing or the hopper.

Mechanical seals arranged in a row. Available in "back-to-back", "face-to-face" or "tandem" sequence.

Ready-to-install pre-assembled units with supply connections and attachment brackets for quick replacement.
