Technical data
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.


  • 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-vibration and low-noise monobloc design with lantern and rigidly connected standard motor (norm motor).
  • Pump housing and lantern with cataphoretic coating as standard
  • Pedestal screwed onto the pump up to a motor power of 4 kW; from a motor power of 5.5 kW, feet screwed to the motor
  • 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. +110 °C and also for oil proportions in the water-glycol mixture.

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
  • Setpoint and speed adjustment
  • Selecting the operation and control mode
  • Configuration of operating parameters
  • Fault acknowledgement

Additional functions

  • Interfaces: Control input "Overriding Off", analogue input 0–10 V, 2–10 V, 0–20 mA, 4–20 mA for constant speed (DDC) or for remote setpoint adjustment, IR interface for wireless communication with operating and service unit Wilo-IR-Monitor/IR-Stick, plug-in slot for Wilo IF modules for connecting to building automation, configurable, potential-free fault and run signal
  • Three-phase AC motor with frequency converter
  • Integrated dual pump management
  • Integrated full motor protection (PTC thermistor sensor) with trip electronics
  • Standard condensate drainage holes in the motor housing (closed upon delivery)
  • Different operating modes for heating (HV) or air-conditioning (AC) applications
  • Access disable on the pump
  • Different operation levels: Standard/service


  • Supporting blocks for fixing to the base
  • IR-Monitor
  • IR-Stick
  • IF module PLR
  • IF module LON
  • IF module Modbus
  • IF module BACnet
  • IF module CAN
  • Control systems VR-HVAC/CCe-HVAC/SCe-HVAC
