Wilo-Comfort-Vario COR-1 MVIE...-GE

Wilo-Comfort-Vario COR-1 MVIE ...- GE - Ready-to-connect water supply system with vertically arranged, non-self-priming high-pressure centrifugal pumps

Overview

  • System reliability through the use of high-pressure stainless steel MVIE series centrifugal pumps with built-in air-cooled frequency converter
  • Extremely wide frequency converter control range
  • Integrated full motor protection by means of PTC thermistor
  • Integrated dry-running detection with automatic shut-down in case of absence of water supply in accordance with the electronic motor control wattage

Type

Connection-ready water-supply unit with vertically arranged, normally aspirated MVIE 70 or 95 series centrifugal pumps, with integrated, air-cooled frequency converter.

Application

  • Fully automatic water supply and pressure boosting system for domestic, commercial, industrial and civil applications (back-up pump acc. to DIN 1988 and DIN EN 806 must be provided).
  • The permissible pumped liquid is generally water that does not have aggressive chemical and mechanical effects on the materials used and does not contain abrasive and long-fibre constituents, such as
    • Drinking water (depending on drinking water tolerances, see Materials section)
    • Clean water
    • Cooling water
    • Process water
    • Extinguishing water (except water for fire extinguishing systems according to DIN 14462; with the approval of the local fire department)

Equipment/function

  • 1 MVIE series pump (70 or 95) with frequency control via integrated frequency converter on a galvanized steel base frame for height-adjustable operation.
  • All parts in contact with the pumped liquid are corrosion resistant
  • On the pressure side:
    • Shut-off valve.
    • Non return valve
    • Nonreturn valve
    • Expansion vessel 8 l diaphragm, PN 16
    • Pressure sensor 4...20 mA
    • Pressure gauge
    • Suction side:
    • Pressure sensor 4...20 mA
  • Pressure gauge
    • Pressure gauge: Pressure gauge on suction side: Pressure sensor 4.20A
    • Manometer

Supply includes

  • Pressure boosting system ready for connection and tested for fault-free function and tightness, mounted at the factory
  • Packaging
  • Installation and operating instructions

Description/structure

Foundation frame: Made of galvanized steel, with height-adjustable anti-vibration mounts, ensuring good structure-borne sound insulation, as well as integrated rigging points.

Piping: On the pressure side there is a complete stainless steel piping system, suitable for connection of all materials used in building services equipment; the piping is designed in accordance with the total hydraulic capacity of the pressure boosting unit.

Pumps: One MVIE 70 and MVIE 95 series pump each.

Air-cooled frequency converters on the pump motor provide infinitely variable speed control between 25 Hz and a maximum of 60 Hz for all pumps of these series. 60 Hz. All pump parts in contact with the pumped liquid are made of stainless steel/grey cast iron with cataphoresis coating and ACS approval (see section "Material description").

Fittings: On the pressure side the pump is equipped with a ball shut-off valve with DVGW approval mark or a ring gate valve and a non-return valve with DVGW approval.

Diaphragm pressure vessel 8 l/PN 16 located on the discharge side, with a butyl rubber diaphragm, DVGW/KTW approval, compliant with food safety laws, equipped with a shut-off ball cock for inspection and testing purposes, with a drainage system and flow fittings with DVGW/KTW approval to DIN 4807.

Pressure monitoring: 2 pressure sensors 4 ... 20 mA, arranged on suction and pressure side.

Pressure display: Pressure gauge located on the suction and final pressure sides.
