Tender text

Single-stage glanded centrifugal pump in monobloc design for installation on a base including foot on the pump housing.

Low-oscillation and low-noise monobloc design with lantern and rigidly connected standard 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.

Supporting block motor H90 BG.160
    

Supporting blocks for installation on a base of monobloc pumps. Comprised of several supporting blocks (number dependent on the pump type), intended for the screwed connection with the screw-on bases or feet of the pump/motor. The supporting blocks ensure secure fastening of the pump to the foundation. Various sets are available for the pump and motor.

Furthermore, they equalise the difference in height between the pump and the motor, if the pump housing is bigger than the axle height of the motor or vice-versa. This prevents turbulent running of the pump and possible premature wear of the mechanical seal.

The set does not contain any fixation material.

Scope of delivery

  • Supporting blocks
  • Washers
  • Alignment plates
  • Screws (type depends on the base of the motor)
