Motor 1 CV single-phase M80 (750 W) for rotary pump RO 1000, ref. ROEU-MOTEUR-862-MONO-1CV

Overview

This monophasé electric motor (750 W (1 CV), ref. ROEU-MOTEUR-862-MONO-1CV) drives the RO rotary pumps through an adapter and a coupling. Robust and compact, it ensures steady rotation of the pump body for constant flow and pressure. The monophasé model is chosen according to the available supply and the required power; it mounts onto the pump via the matching flange adapter and coupling (M71/M80) for an aligned, durable assembly.

Operation & performance

Rotary vane pumps offer steady flow and good tolerance to continuous running. Flow and pressure depend on the model and motor speed; the body (brass, bronze or stainless) is chosen by water quality and required corrosion resistance. The pump + motor + coupling assembly is sized to the desired flow and working pressure.

Installation & maintenance

Mount the pump on a stable support, couple it to the suitable motor, respect the rotation direction and connect suction/discharge (BSPT/NPT by model). Check tightness, avoid dry running and ensure alignment. Periodic maintenance (vanes, seals, coupling) extends service life; wear parts are available in the catalogue.

Materials & options

Body available in brass, bronze or stainless (AISI 303/304) by required corrosion resistance. Threaded BSPT or NPT connection. Flows from 150 to 1000 L/h. Single- or three-phase motors (300 W to 1 HP) and M71/M80 adapters/couplings complete the range.

Safety & good practice

Protect the pump against dry running and overcurrent (motor thermal protection recommended). Filter the water upstream to preserve the vanes and body, bleed the air at commissioning and regularly check tightness and running noise. Respect the indicated voltage and frequency and connect the motor earth.

Compatibility & assembly

The pump, motor and coupling form one assembly: check the flange match (M71/M80), the rotation direction and the supply type (single/three-phase) before mounting. Flows range from 150 to 1000 L/h; pair the pump with the correctly rated motor and the matching coupling for reliable, quiet operation. When in doubt about the flange size or power, our team confirms the right combination for your setup.

Applications

These rotary pumps and their motors equip RO units, boosters and small water-treatment installations (residential, commercial, light industry, agriculture). They feed reverse-osmosis membranes, provide circuit boosting and dosing, with stable flow and compact mounting.

Choosing right

Choose the flow (150 to 1000 L/h), the body material (brass, bronze, stainless by corrosion) and the motor (single/three-phase, power) to suit your installation. Don’t forget the adapter and coupling matching the motor flange (M71/M80). The DIMM team helps you size the pump + motor assembly.
