CR-centrifugalpumpe – vertikal flertrinspumpe

Beskrivelse

Beskrivelse

CR flertrins centrifugalpumper kan anvendes i både vandforsyning, vandbehandling og de fleste industrielle løsninger, hvor der er tale om både højt tryk og/eller farlige, brandbare eller aggressive væsker.

Pumperne leveres i både støbejern og rustfrit stål (nogle varianter fås også i 100 % titanium). Pumpedele, som typisk er sårbare over for vanskelige medier eller særligt krævende driftsbetingelser, kan skræddersys til anvendelse under særlige forhold.

CR

CR-serien består af 16 flowstørrelser, som kan skabe tryk på op til næsten 50 bar, samt et stort udvalg af akseltætninger, gummimaterialer og forsyningsspændinger. Leveres med standardmotor (IE3).

Den nye ekstra store CR-serie består af 6 nye flowstørrelser: 95, 125, 155, 185, 215 og 255 (hvoraf 95, 125 og 155 erstatter tidligere størrelser 90, 120 og 150).

Med de nye størrelser får du ikke kun markant forbedret hydraulisk design, som vil øge effektiviteten og dermed spare penge i det lange løb. Du får også næsten en fordobling af flowområde og tryk.

CRE

CRE-pumperne kommer med den seneste MGE-motor, som er 100 % skræddersyet til pumpen og IE5-godkendt – den højeste virkningsgrad på markedet for elmotorer. Motorerne kommer med indbygget frekvensomformer eller ekstern frekvensomformer (CUE). Frekvensomformeren betyder, at dit anlæg ikke bruger mere energi end nødvendigt.

Motoren, der anvendes, er normalt en standard IE3-motor. Motoren fås dog også i en IE5-version med permanentmagnet-motor op til 22 kW.

CRE GRUNDFOS - Intelligent Efficiency by Grundfos

GRUNDFOS CRE - INTELLIGENT EFFICIENCY BY GRUNDFOS (Product brochure)

The renowned CRE pump has been upgraded with the latest motor technology to offer impressive energy efficiency that exceeds the IE4 levels, even including the energy consumption of the variable frequency drive.

CRE, CRIE, CRNE - MGE motor update

CRE, CRIE, CRNE (MGE motor update) (Data Sheet)

The new MGE represents a new way of thinking about speed-controlled motors when it comes to efficiency. The total efficiency of this new motor, including the frequency converter, is higher than the IE4 level defined by the IEC 60034-31, even though this standard only applies to the motor. This will make the MGE unique for its class when it comes to efficiency.

CRN Air-Cooled Top (Product brochure)

Air-cooled Top: The Grundfos CRN Air-Cooled Top is specially designed to handle hot liquids; i.e. 120 °C - 180 °C. To make sure that the liquid temperature around the shaft seal does not exceed the level it can withstand, the pump is fitted with a special air-cooled shaft seal chamber generating the same insulation effect as the one of a thermos. To cool the pump, no external cooling is necessary; the ambient temperature is sufficient.

CR – ATEX-godkendte CR-pumper

ATEX approved CR pumps (Product brochure)

The ATEX approved CR pumps and motors carry a mark that shows which explosion category the pumps are designed for, and thus, in what kind of areas they can be used. The directive distinguishes between two explosion groups; group I and II. Whether it is a group I or II pump, depends on the level of danger of explosion in the area in which the CR pump is installed.
