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 for pumping water up to Tmax = +140 °C. Up to T ≤ +40 °C, a glycol admixture of 20 % to 40 % by volume is permissible. An alternative mechanical seal must be provided for water-glycol mixtures with a glycol content of > 40% to max. 50% by volume and a fluid temperature of > +40 °C to max. +120 °C or other fluids that differ from water. When using water-glycol mixtures, the use of an S1 variant with a corresponding mechanical seal is generally recommended.

Base pump housing
Base pump housing
Supporting block pump housing H20 (50/200)
    

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)
