Mechanical seals are used in industrial pumps, compressors, and other applications where a spinning shaft protruding into a wetted process is likely to have continuous, rigorous duty. Mechanical seals move the point of the seal away from the shaft to specially designed sealing …

Useful information on pump shaft seals What is a pump shaft seal? Shaft seals prevent liquid escaping from a rotating or reciprocating shaft. This is important for all pumps and in the case of centrifugal pumps several sealing options will be available: packings, lip seals, and all types of mechanical seals – single, double and tandem including cartridge seals.

This article will explain what a mechanical seal is and the key design features that make them work. Basics of fluid pump sealing. A mechanical seal is simply a method of containing fluid within a vessel (typically pumps, mixers, etc.) where a rotating shaft passes through a stationary housing or occasionally, where the housing rotates around the shaft.

The other face rotates with the shaft to provide the primary seal. Axial mechanical force and fluid pressure maintain the contact between the seal face materials. This contact prevents leakage and retains the fluid within the pump. The Three Types of Mechanical Seals. Three types of mechanical seals are used in process equipment: Cartridge ...

The advantage of our types of pumps for sewage sludge is the lateral suction on the horizontal design. It is perfect to optimally manage the supply and discharge pressure, so to guarantee a real benefit to the mechanical seal. These types of sludge pump can reach a flow rate of 1500 m3 / h.

Provides specifications, materials, applications and performance comparisons for different types of rotary and linear pump seals for a wide variety of speeds, pressures, fluids, temperatures

Single, double, tandem and tandem seal with intermediate labyrinth arrangement available; An ideal solution for Ethane, CO2 and many other low vapor margin applications; This type of seals can handle both liquid and gaseous phases during the operation of the pump

A few basic components and principles in mechanical seal design contribute to a working seal at the interface of the rotating shaft and stationary pump/mixer/seal-chamber housing. Mechanical seals are usually end-face seals or rotating-face seals, but in some designs they can be circumferential or even a hybrid of lip-type seals.

Our pump seals thrive under pressure. At All Seals we know down time is not an option. We specialize in hard-to-find seals and demanding applications. With over 40 years of experience in supplying quality replacement mechanical seals, we can help you identify the …

Single mechanical seal - this is the most common seal type used which is a seal used to seal the pump head, ensuring the liquid is retained within the pump …

Built for high-speed pump and valve applications, these super-tough seals are made of expanded-graphite yarn with carbon-yarn corners. Heat-Shielding Chemical-Resistant Packing Seals. Also known as GFO, these expanded PTFE seals contain graphite powder, which dissipates heat away from the shaft and allows pumps to run cool at high speeds.

Pump Seals. Single Spring Mechanical Pump Shaft Seals are the most common type of pump seal. It was the first designed and became a stapel for industrial pumps. The most significant modifications to the original design of single spring seal are the seal faces.

1. Types of shaft seals Almost everywhere where pumps with rotating shafts are used, a shaft seal is involved. The shaft seal forms a barrier between what is inside the pump and the atmosphere. A pump with a through-shaft is not completely sealed. It is a challenge …

Mechanical seals are distinct from other types of seals because it involves a rotating part, a stationary part and a spring. The seal is the interface between the moving and stationary parts. Sealing the junction of a moving and a stationary part is a challenge, to say the least, and the spring is there to ensure adequate pressure on the parts to maintain the seal despite the movement.

The shaft seal is a sealing element which seals the rotating shaft of a centrifugal pump where it passes through the non-rotating pump casing, reducing fluidleakage to atmosphere or the entry of air from outside to a certain level, and keeps wear of the sealing faces as low as possible.. Pumps are specially designed and manufactured to cater for a whole range of different applications.

such as Centrifugal and Liquid Ring pumps. These pump types do not impose any radial or axial constraints on seal design. However on Rotary Lobe type pumps the need to minimise the shaft extension beyond the front bearing places significant axial constraints. If this were extended, the shaft diameter would increase introducing a radial

Elastomer Rubber Bellow Mechanical Seals. Developed with rubber bellow, this type of seal is widely used for water, oil and other light duties applications. Both standard and OEM elastomer bellows seals are available.Most of our rubber bellow seals can easily replace your pump seal. Elastomer Bellow Seals R11. Elastomer Bellow Seals R12.

The shaft seals in any pump that the electric motor drives are ones that do need maintenance and replacement, whatever type of pump it is. If the pump moves liquids, such as a centrifugal water pump, it is important that the seal doesn't leak although in some applications a small amount of leakage can be tolerated.

This pump type requires no seal, and keeps the liquid inside the tube, so zero leakage. 0.2 - 200 gpm----- .78 - 757 lpm. 10 - 250 psi-----.7 - 17 bar. 0.125 - 40 hp: Piston Pumps: Piston pumps are a type of reciprocating positive displacement pump that has, double acting reciprocating pistons.

Mechanical seals vs. pump packing? Which is the best and most effective sealing technology for your pump or agitator application? Long ago, companies didn't want to switch to mechanical seals because of the complicated installation and need to completely disassemble the equipment. The invention of cartridge and split mechanical seals effectively eliminated those …

The stationary part of the seal is fitted to the pump housing with a static seal, this may be sealed with an o-ring or gasket clamped between the stationary part and the pump housing. So sealing points in the seal design are straightforward and static seals. The rotary portion of the seal is conserved onto the shaft typically using an O ring.

Basic components of pump seal; Essential components of a pump seal are rotating the shaft and stationary pump or mixer or seal-chamber housing. Mechanical seals are rotating-face seals or end-face seals. In some designs, hybrid of lip-type seal or circumferential seals are used. Regardless of the seal type you use, the following components are ...
