Tender text

Single-stage glanded centrifugal pump in monobloc design for an installation on a base with integrated frequency converter for an electronic control for constant or variable differential pressure (Δp-c/Δp-v). The CronoBloc BL-E has been predominantly designed for pumping heating water (acc. to VDI 2035), cold water and water/glycol mixtures without abrasive substances in heating, air-conditioning and cooling systems.

Design

  • Single-stage low-pressure centrifugal pump
  • Spiral housing in monobloc design with flange and housing dimensions according to DIN EN 733, flanges PN 16 – according to EN 1092-2
  • Low-oscillation and low-noise monobloc design with lantern, foot on pump housing and rigidly connected standard motor
  • All grey cast iron components with cataphoretic coating as standard
  • Direction-of-rotation-independent bellows mechanical seal with forced flushing and cavitation-reducing impeller.
  • Mechanical seal for pumping water up to Tmax = +140 °C. A glycol admixture of 20% to 40% by volume is permissible up to T ≤ +40 °C. An alternative mechanical seal must be provided in water-glycol mixtures with glycol proportions > 40 % up to max. 50 % by volume and a fluid temperature of > +40 °C up to max. +120 °C or fluids other than water. When using water-glycol mixtures, the use of an S1 variant with a corresponding mechanical seal is generally recommended.

Wall fixation/installation on a base (1)

Base motor
Base motor
Supporting block motor H20 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)
