PTFE guide and wear strip

ODU Piston seals are work to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.

The pump plunger sealing system is adopted in the pump, which can effectively prevent the damage caused by water leakage and prevent the pump failure caused by the plunger friction overheating.    

T-Seal is a compact three-piece double acting seal composed of a T shaped elastomeric element and two rigid anti-extrusion rings. These compact sealing elements are designed for installation in simple O-ring grooves and are often used to modify faulty O-rings.

FFKM O-ring is a circular seal made of perfluoroelastomer compound, with a higher fluorine content than FKM fluoroelastomer.

The spring energized seal is a high-performance Teflon seal with a special spring inside.

JST's back up ring compensate for large temperature fluctuations. Using Back-up Rings allows O-Rings to be utilized in higher pressure applications, where larger extrusion gaps are required and where there are reciprocating or rotating movements. Back-up Rings are protective and supporting elements with no sealing function. The back up ring material could be  PEEK, modified PTFE.

Wear rings are used to help keep the piston centered, allowing for even wear and pressure distribution on the seals. Wear rings are used in both piston and rod applications.

Lockdown screw seal is used mainly in geothermal applications, HNBR packing with stainless steel caps provide superior performance over metal pressure seals.
