Spinning pump

product details


Spinning pump is a kind of gear type metering pump, which is one of the key parts of spinning machine. Its main purpose is to transport spinning melt evenly and equivalently to spinning assembly, and then solidify into silk through spinneret micropore cooling.


Applicable industry of spinning pump


Spinning polyester, polypropylene, nylon filament staple, POY and FDY filament.

Product features


Spinning metering pump is composed of plate, gear, shaft, drive sleeve, fixed sleeve, cover plate and other parts. In operation, the pump is transported by melt for self lubrication. Various parts are closely matched to form mechanical seal, which can prevent melt leakage. The transmission of the pump depends on the special drive shaft joint on the spinning machine and the drive sleeve of the pump. The pump should be placed in a clockwise direction and should not be reversed. Before delivery, all the metering pumps are qualified in the special flow testing machine. In order to improve the fiber quality, the flow rate of the metering pump must be measured and grouped after each loading and unloading cleaning of the metering pump and before the use of the spinning machine.
