German KLINGER seals KLINGER models KLINGER prices

KLINGER seals are a type of friction seal or stuffing box used to prevent liquid leakage between the shaft and bearing of compressors or other fluid handling equipment. They are also sealing devices designed to prevent leakage at the pump shaft and housing. Common types of shaft seals include packing seals, mechanical seals, and power seals. The shaft seal of a reciprocating pump is typically a packing seal. When transporting media where leakage is not permitted, diaphragm reciprocating pumps can be used. The shaft seals of rotary pumps (including vane pumps, rotor pumps, etc.) mainly consist of packing seals, mechanical seals, and power seals.

Features of KLINGER seals

1) No need to measure the working length of the seal during installation; 2) The shaft can be adjusted at any time; 3) Leakage issues during startup do not occur because the seals have been pre-tested; 4) During installation, only the bolts securing the seal cover need to be tightened, making it easy to ensure assembly quality; 5) Protects the sealing surface from contamination by debris or damage due to operational errors before installation or startup; 6) Can be readjusted after thermal expansion of the machinery; 7) Self-centering through fit; 8) Easy removal of the seal for cleaning and inspection without disassembling the pump equipment. The API682 standard recommends using cartridge mechanical seals for all mechanical seals.

Preparation for starting KLINGER seals

1) Thoroughly inspect the mechanical seal, auxiliary devices, and pipeline installations to ensure they are complete and meet technical requirements. 2) Perform a static pressure test on the mechanical seal before startup to check for leaks. If there is significant leakage, identify the cause and attempt to resolve it. If ineffective, dismantle and reassemble. Generally, the static pressure test uses 2~3 kg/cm². 3) Rotate the pump according to its direction to check if it moves smoothly and evenly. If rotation is difficult or impossible, verify whether the assembly dimensions are incorrect or the installation is unreasonable.

Functions and applications of KLINGER seals

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) differential pinion oil seal Rear wheel oil seal Front wheel oil seal Steering gear oil seal (steering gear repair kit o O-rings) Power steering oil seal (front half-shaft oil seal). Any rotating component with internal lubricating oil that connects to the exterior requires an oil seal. Some are made of rubber, others of metal, but most are steel-reinforced rubber, such as rear crankshaft oil seals, front and rear transmission oil seals, left and right half-shaft oil seals, main reducer front oil seals, air compressor crankshaft oil seals, etc.
