Single-stage glanded centrifugal pump with in-line design for pipe installation or installation on a base. Low-oscillation and low-noise close-coupled design with lantern and rigidly connected standard flange motor. With force-flushed, bidirectional bellows mechanical seal (from 37 kW/4-pole, optionally available with a cartridge mechanical seal in back pull-out design for mechanical seal replacement without dismantling the motor) and cavitation-reducing impeller. 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.
