A mechanical seal pump could potentially save you a lot of annual costs. Given the general geometry of a mechanical seal, anywhere that there’s a gasket or an o-ring, there ensues a potential leak point: An eroded, worn, or fretted dynamic o-ring (or gasket) as the mechanical seal moves. Dirt or contamination in between the mechanical seals.

UNDERSTANDING MECHANICAL SEALS

SEAL TYPE • The mechanical seal shown in the pump photograph is a Type “1” mechanical seal. Probably the most widely recognized and also most common mechanical seal used in general service, low pressure applications. • At Utex, we refer to this type as RS-1 • The assembly shown in the pump is configured with a

Mechanical Seal for Pumps Flowserve Mechanical Seal …

A mechanical seal flush is a piping set-up on a pump and seal assembly where a flow is induced in the seal chamber in order to improve MTBF of the mechanical seal. It is used to improve cooling, heating, remove solids and increase pressure (in combination with a neck or throat bush).

Useful information on pump shaft seals

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.

What is a Mechanical seal? | AESSEAL

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.

Understanding The Basics of Mechanical Seals Vs. Packing

Read on for a basic understanding of mechanical seals, and how they differ from packing. WHY DO PUMPS NEED TO BE SEALED? In order to understand why pumps need to be sealed, let's go back to some pumping basics and review how a centrifugal pump operates. Fluid enters a centrifugal pump through the suction nozzle at the center of a rotating impeller.

Back to Basics: Mechanical Seals | Pumps & Systems

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.

Centrifugal pump - Wikipedia

Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. They are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller ...
