Timmer-Pneumatik seals are sealing devices installed to prevent leakage between the pump shaft and the housing. Common types of shaft seals include packing seals, mechanical seals, and power seals. The shaft seal of a reciprocating pump is usually a packing seal. When transporting media where leakage is not permitted, a diaphragm reciprocating pump can be used. The shaft seals of rotary pumps (including vane pumps, rotor pumps, etc.) mainly include packing seals, mechanical seals, and power seals.

Timmer-Pneumatik Seals Introduction

A mechanical seal is a shaft sealing device for rotating machinery, such as centrifugal pumps, centrifuges, reaction vessels, and compressors. Since the drive shaft passes through the interior and exterior of the equipment, there is a circumferential gap between the shaft and the equipment. Media inside the equipment leaks outward through this gap; if the pressure inside the equipment is lower than atmospheric pressure, air leaks into the equipment. Therefore, a shaft sealing device is required to prevent leakage. There are many types of shaft seals. Due to advantages such as low leakage and long service life, mechanical seals are the primary shaft sealing method for these equipment worldwide. Mechanical seals are also called face seals. They are defined in relevant national standards as: "a device that prevents fluid leakage, formed by at least one pair of faces perpendicular to the axis of rotation maintaining contact and sliding relative to each other under the action of fluid pressure and the elastic force (or magnetic force) of a compensation mechanism, along with auxiliary seals."

Timmer-Pneumatik Seal Structure and Composition

1) Main components: rotating ring, stationary ring, cooling device, and compression spring (depending on the specific equipment). 2) Auxiliary seals: sealing rings (including O-shape, X-shape, U-type, wedge shape, rectangular flexible graphite, PTFE-covered rubber O rings, etc.). 3) Elastic compensation mechanism: springs, thrust rings, spring seats, keys, or various screws. 4) Classification: divided into single-face and double-face; balanced and unbalanced; arbitrary rotation direction and fixed rotation direction.

Timmer-Pneumatik Seal Functions and Applications

Engine: crankshaft - front and rear crankshaft oil seals; valve - valve oil seals (engine repair kit o O-rings) (distributor oil seal, water pump oil seal, balance shaft oil seal, oil pump oil seal...); camshaft - camshaft oil seal; Transmission: transmission - front and rear transmission oil seals; shift lever oil seal (transmission repair kit o O-rings) (transfer case - front and rear transfer case oil seals); Rear axle: half shaft - rear half shaft oil seal; differential - (front) rear pinion oil seal; rear wheel oil seal; front wheel oil seal; steering gear oil seal (steering gear repair kit o O-rings); power steering booster oil seal (front half shaft oil seal). Oil seals are required wherever a rotating housing contains liquid lubricating oil and connects to the exterior. Some are made of rubber, some of metal, but most are steel-cased rubber, such as rear crankshaft oil seals, front and rear transmission oil seals, left and right half shaft oil seals, front main reducer oil seals, and air compressor crankshaft oil seals.
