German carl schloesser seals, carl schloesser models, carl schloesser prices

carl schloesser seals are sealing devices installed to prevent leakage between the pump shaft and the housing. Common shaft seal types include packing seals, mechanical seals, and dynamic 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 consist of packing seals, mechanical seals, and dynamic seals.

Introduction to carl schloesser seals

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. National standards define them as: "A device that prevents fluid leakage by maintaining contact and relative sliding between at least one pair of faces perpendicular to the rotation axis, under the action of fluid pressure and the elastic force (or magnetic force) of a compensation mechanism, in conjunction with auxiliary seals."

Structure and composition of carl schloesser seals

1) Main components: rotating ring, stationary ring, cooling device, and compression spring (depending on the specific equipment). 2) Auxiliary sealing elements: O-rings (including O-shaped, X-shaped, U-type, wedge-shaped, rectangular flexible graphite, PTFE-covered rubber O rings, etc.). 3) Elastic compensation mechanism: springs, push 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.

Common questions about carl schloesser seals

Preventing leakage through sealing is a perpetual pursuit for chemical equipment. It is this requirement that has led to the increasingly widespread adoption of magnetic drive pumps and canned motor pumps. However, there is still a long way to go to truly achieve zero leakage. For example, issues such as the service life of the isolation sleeve in magnetic drive pumps and the can in canned motor pumps, pitting corrosion of materials, the need for sealing materials with good corrosion resistance, and the reliability of static seals. The following is a brief introduction to some basic situations regarding sealing: 1. Sealing types For static seals, there are usually only two types: gaskets and O-rings. Among O-rings, the O-type ring is the most widely used; for dynamic seals, chemical pumps rarely use packing seals, but primarily use mechanical seals. Mechanical seals are further classified into single-face and double-face, as well as balanced and unbalanced types. Balanced types are suitable for sealing high-pressure media (typically referring to pressures greater than 1.0MPa). Double-face mechanical seals are mainly used for media that are high-temperature, prone to crystallization, viscous, contain particles, or are toxic and volatile. For double-face mechanical seals, a barrier fluid should be injected into the seal chamber. Its pressure is generally 0.07 to 0.1MPa higher than the medium pressure. 2. Sealing materials For static seals in chemical pumps, fluororubber is generally used. PTFE materials are used only in special cases. The material configuration of the rotating and stationary rings in mechanical seals is critical. It is not necessarily best to pair cemented carbide with cemented carbide. High cost is one aspect; furthermore, having no hardness difference between the two is also unreasonable. Therefore, it is best to handle them differently according to the characteristics of the medium (Note: The American Petroleum Institute API610 Eighth Edition provides relatively detailed provisions for typical configurations of mechanical seals and piping systems in Appendix D).
