Single-phase motor have a built-in thermal overload switch.

Three-phase motors must be connected to a motor starter in

accordance with local regulations.

Material:

The material variant (VMS, VMN) should be selected

based of the liquid to be pumped.

VMS wetted parts are made of AISI304/AISI316.

VMN inlet and outlet chamber is made of cast-iron and

wetted parts are made of AISI304/AISI316.

Viscosity:

The pumping of liquids with densities or kinematic

viscosities higher than those of water will cause a

considerable pressure drop, a drop in the hydraulic

performance and a rise in the power consumption.

Pump:

VMS/VMN are a kind of non-self priming vertical multistage

centrifugal pump, the pumps are available with standard

motor, the inlet and outlet are located at the pump bottom at

the same plane (inline type). all pumps are equipped with a

maintenance-free mechanical seal set of the cartridge tyre.

Terminal Box Positions:

As standard the terminal box is mounted on the suction

side of the pump, meanwhile, 0, 90, 180, 270 could be

adjusted according to the following proceeding:

1. If necessary, disassembling the protective cover of the shaft

connector, but not disassembling the shaft connector.

2. Disassembling the motor fixation screws.

3. Turn the motor to the required direction.

4. Fasten the motor screws.

5. Install the shaft connector's protective cover.

The voltage and frequency are marked on the label, the

correct power should be confirmed with the label before

usage.

To ensure the electric connection is conformity to the

drawing marked on the label inside the terminal box.
