Tender text

Single-stage glanded centrifugal pump in close-coupled 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), chilled 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 close-coupled design with flange and housing dimensions according to DIN EN 733, flanges PN 16 – according to EN 1092-2
  • Low-oscillation and low-noise close-coupled 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.

Accessories

  • Supporting blocks for fixing to the base
  • IR-Stick
  • IF module PLR
  • IF module LON
  • IF module Modbus
  • IF module BACnet
  • IF module CAN
  • Control system VR-HVAC
  • Control system CCe-HVAC
  • Control system SCe-HVAC
  • Differential pressure sensor (DDG)

Standard equipment

Pump display for indication of:

  • Control mode Δp-c (constant differential pressure), Δp-v (variable differential pressure), PID controller, n-constant (constant speed)
  • Setpoint (e.g. differential pressure or speed)
  • Error and warning messages
  • Actual values (e.g. power consumption, actual value of the sensor)
  • Operating data (e.g. operating hours, energy consumption)
  • Status data (e.g. status of SSM and SBM relay)
  • Device data (e.g. pump name)
  • Operating mode (for Y-piece installation only: main/standby operation, parallel operation)

One-button manual operation level for:

  • Pump On/Off
