The double-acting piston sealing set ZP consists of a rubber-fabric seal with back-up rings on both sides to prevent extrusion. The dynamic surface of the seal on the outer diameter is reinforced with a special dimensionally stable fabric. This supports the development of a lubricating film between the seal and the cylinder wall, even after long standstill periods and under high pressure. This grease deposit reduces breakaway friction and dynamic friction and thus wear of the dynamic surface of the seal. The surface structure ensures wear resistance, even in low-lube conditions. The ZP sealing set is extremely robust, even in harshest conditions such as particle contamination in the system.

Multiple-lip (chevron) Seals or Vee Packings that consist of a group of endless rings and are usually used for sealing rods, pistons, plungers in hydraulic cylinders and hydraulic presses. V-Packings are used for low or high pressure applications with Single or Double acting cylinder.
V-Packings are also used in various Oilfield Downhole equipment such as various Valves etc. V-Packings are extremely suitable for usage in medium to heavy duty applications. Vee Packings accept low and high pressure while operating in the most extreme conditions and also if there exists any misalignment between the sealing gaps.
The hinge-line action of Vee-Packings that enables immediate reaction even to minor pressure changes is very distinctive and exclusive to a Vee-Packing design. Each individual lip of a Vee-Packing set reacts independently to pressure thus effecting aseal automatically. In case of multiple lip configurations, pressure is automatically distributed thus effecting a seal along the shaft. Vee-Packings also premit automatic reaction to shocks from high pressure and overloads.
The Vee-Packing is a combination of Base Seal, the Vee-Ring at the center and the Pressure ring. The Vee-Ring is the main seal that can retain high and low pressures while the base seal supports the center ring from getting extruded during high pressure applications. The Pressure Ring helps in retaining the Vee Packing profile and distributing pressure equally.

Well Service Packing was developed to eliminate extrusion and provide excellent abrasion resistance for fracturing, acidizing, and cementing pumps; and it delivers maximum sealability for high-pressure well service pumps.
We produce well service packing replacements for mud pumps. The pressure rings, header rings and female adapters are designed to retrofit current plunger sizes and designs. we deliver superior quality materials and workmanship to keep your equipment running longer. In addition custom machined shapes (lantern rings, spacers) can be engineered to meet your total sealing system requirements.
