Model NO- TM-006


The “ Metlor” ” designed and developed gear pump is the most widely used of the positive action rotary pumps. Two gear wheels operate inside a casing. One is driven while the other rotates in mesh with it. The liquid is carried around in the space between consecutive teeth and then ejected as the teeth mesh. The pump has no valves. It is a positive displacement pump and will deliver against high pressures. The output is a more even flow than that of a reciprocating pump. It is particularly suitable for high-viscosity fluids.

A motor-driven gear pump, mounted on a stainless steel plinth with a water reservoir and pipework for continuous circulation. The pump head and the water reservoir are manufactured from clear acrylic for maximum visibility.

The pump speed is accurately controlled by an advanced electronic inverter This inverter also calculates the torque produced at the motor drive shaft, allowing the power used by the pump to be derived. The conditioning electronics for the sensors and allows their readings to be displayed on the computer software.
