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.

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

Accessories

  • 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
  • Differential pressure sensor (DDG) sets 0-10 V for pumps in version ...-R1
