Wilo-COE-2 MHIL BC

Series description

Your advantages

High operational reliability, thanks to system with two horizontal multistage MHIL pumps with stainless steel hydraulics

Highly efficient EC motor with IE3 class for three phase motors from 0.75 kW and larger

Drinking water approval (ACS) for pumps with components made of stainless steel that come into contact with the fluid

Simple operation thanks to Basic Control switchgear with all necessary functions

Construction

Ready for connection, non self-priming water-supply unit with 2 parallel-switched, horizontally arranged high-pressure multistage centrifugal pumps with fixed speed in glanded design of the MHIL series, equipped with BC switchgear.

Application

  • Fully automatic water supply and pressure boosting in residential buildings and small commercial locations.
  • Pumping of drinking water and clean process water and other water mixtures that do not chemically or mechanically attack the materials used and do not contain any abrasive or long-fibre constituents.

Equipment/function

  • Two pumps of the MHIL 3 to MHIL 5 series per system with an IE3 standard motor for 3~ motors and IE1 for 1~ motors
  • Automatic pump control with BC switchgear specially for the pump management with fixed speed
  • Components that come in contact with the fluid are corrosion resistant.
  • Base frame made of galvanised steel
  • Pipework made of galvanised steel
  • Stop valve on the suction and pressure side of each pump
  • Non-return valve on the pressure side of each pump
  • Pressure switch on the pressure side
  • Pressure gauge on the pressure side
  • Optional low-water cut-out switchgear on the suction side

  • Pump housing made of cataphoretic-coated grey cast iron EN- GJL 250
  • Shaft made of stainless steel 1.4028
  • O-ring seals made of EPDM
  • More information on the pumps can be found in the "Pressure boosting" chapter.

Description/construction

  • Base frame: made of galvanised steel, to be fastened to a concrete foundation
  • Pipework: Complete pipework made of galvanised steel, suitable for the connection of all standard pipe materials; the pipework is designed according to the hydraulic output of the pressure boosting system.
  • Pumps: Two pumps of the MHIL 3 to MHIL 5 series switched in parallel; all pump components that come in contact with the fluid are made of stainless steel/cataphoretic-coated grey cast iron. ACS approval for all components that come into contact with the fluid. More information on the pumps can be found in the "Pressure boosting" chapter.
  • Valves: Each pump is equipped with an ACS-tested ball shut-off valve on the suction and pressure side and with an ACS-tested non-return valve on the pressure side
  • Diaphragm pressure vessel: A diaphragm pressure vessel is to be designed and installed according to the installation situation.
  • Pressure sensor: A pressure sensor is installed and connected to the BC switchgear on the pressure side of each pump.
  • Pressure indication: On the pressure gauge on the pressure side
  • Switchgear: The system is standard-equipped with a BC switchgear.
