Tender text

Single-stage glanded centrifugal pump with in-line design for pipe installation or installation on a base. Low-oscillation and low-noise monobloc design with lantern and rigidly connected standard flange motor. With forced-flow circulation, bidirectional bellows mechanical seal and cavitation-reducing impeller. From kW 37 with a cartridge mechanical seal in the back pull-out system for mechanical seal replacement without dismantling the motor. Flange with R 1/8 pressure measuring connections.

All grey cast iron components are cataphoretic-coated.

Pumps with motors ≥ 5.5 kW are equipped as standard with a PTC thermistor sensor for motor protection.

The motor terminal box ≤ 7.5 kW can be made of metal or plastic. If a metal terminal box is absolutely necessary, please order the appropriate special variant. The motor terminal boxes > 7.5 kW are always made of metal.

  • Mechanical seal S1 recommended for water-glycol mixtures with glycol proportions up to max. 50 % by volume and a fluid temperature of -20 °C up to max. +90 °C ... +110 °C and also if there is oil in the water-glycol mixture.
