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.
