●No mechanical seal structure, which can guarantee the high pressure and high temperature condition not seep materials. Effectively reduce the change screen resistance, reduce hydraulic system pressure of work.

●One-piece structure, without carrying aperture, strengthen bearing pressure, make the system load pressure is higher.

●Using High quality aly selatter nitiding process to extended product lite span greatly. .

●Integral engineering oil cylinder, a long use lite.

●Ater optimization of rheological through cllular plate, to reduce the extrusion process fluid shear.

●Using inner heating device, for safe and energy- saving. Fully enclosed wires,for the elegant appearance.
