Mechanical Rotating Solutions curbs water wastage by installing AESSEAL Single Cartridge Seal

Mechanical Rotating Solutions is often called in to offer solutions to water leakage from pumps due to wear on the stuffing box packing, bearing failure, seal failure, and other related issues. By fitting an AESSEAL SMSS™ Single Cartridge Seal, Mechanical Rotating Solutions is able to eliminate pump leakage whilst also ensuring less maintenance and greater energy efficiency.

Contacted by a client to address excessive water leakage from one of its WARMAN AH Centrifugal pumps MRS selected the AESSEAL SMSS™ Single Cartridge Seal offering as the most suitable for tackling the problem. Due to its versatility, the WARMAN-AH offers a wide range of seal and liner configurations which enabled MRS to tailor a solution to its customer’s specific application.  Excessive gland leaking caused by packing failure determined the choice of the AESSEAL® SMSS™ single monolithic stationary seal. The specific seal provides maximum face stability in high pressure and high temperature applications, improving seal life whilst reducing damage to faces in stop/start applications.

The AESSEAL® range of single cartridge mechanical seals has been specifically designed to eliminate some of the main causes of premature mechanical seal failure.

As a single pump can spill up to 8820 kilolitres of water per annum (7 litres/minute) it is critical to ensure that the chosen sealing solution is the right one for the pump application. AESSEAL High Performance Sealing Solutions as offered by Mechanical Rotating Solutions has helped clients in the Mpumalanga region to ensure significant water, energy and pump downtime savings.

Having more than 7% of annual sales revenue reinvested in R&D over several decades, the AESSEAL® range of products distributed by Mechanical Rotating Solutions has sealed nearly all major equipment types and models. Solutions for some of the more commonly encountered manufacturers include Warman (LabTecta66 WARMAN), KSB (LabTecta66 KSB), Denver Orion and RAPID.

Working with industry stalwarts and OEM manufacturers etc. it becomes evident that not all sealing solutions are the same. Equipment reliability improvements can be made by changing the seal environment and/or upgrading the seal design. Mechanical Rotating Solutions can provide inexpensive seal conversion kits to upgrade non-AES seal designs or change the OEM equipment seal environment in order to dramatically improve seal life.

Fitted to a KSB pump by Mechanical Rotating Solutions, the AESSEAL CSSN™ range of cartridge mechanical seals has been designed as high-performance sealing solutions for general/flush applications.

Over the last decade, Mechanical Rotating Solutions has worked together with various clients changing their sealing methods, improving the reliability of their pumps and reducing the likelihood of breakdowns and downtime. This, in turn, has led to a decrease in maintenance costs.

Among its product offering and related turnkey solutions, Mechanical Rotating Solutions is currently servicing the Mpumalanga area with the AESSEAL® product range of mechanical seals and systems, Labtecta Bearing Isolators, Belzona Engineered Coatings and Superbolts, as well as supplying the whole of South Africa with innovative Straub pipe couplings, and turnkey pumping solutions including KSB pumps and valves, HCP pumps and other world class products.
