Circor provides pumps for medical glove production in China
The NTT pump.

Circor International Inc has recently supplied three NTT 250-400 thermal oil pumps with variable frequency drive (VFD) for use on a medical glove production line in Yingke, China.

The pumps, installed in the heat transfer system, control the temperature while the gloves dry in their molds.

Working together, the application team in Germany and the sales team in China delivered the pumps in just 10 weeks, considerably shorter than average.

At an operating temperature of 280°C and almost atmospheric inlet pressure, the application requires a flow rate of 900 sq m per hour at 55 meters head. The NTT pump’s compact design enables it to operate at 1800 revolutions per minute (rpm), which is necessary to achieve the required flow rate.

Specially designed for thermal oil applications, the NTT pumps can handle high temperature and avoid thermal expansion problems during heat up and cool down phases. The mechanical seals are designed to avoid dangerous spillage of hot oil during normal operation or in the event of seal failures. High temperature anti-friction bearings ensure nearly maintenance free operation. To control the pump speed, the pumps are equipped with a VFD to provide the electrical power at the required frequency to the 4-pole induction-motor.
