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 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.
