Industries we supply and service

Onshore

To be able to cope with sand, water and gases found in crude oil, pumping systems for mineral oil require heavy duty pumps with reliable engineered mechanical seals that feature durable sliding faces with good emergency running characteristics. Often it is necessary to seal pressures in excess of 100 bar and sliding velocities of over 60 m/s. The ideal seal face combination for such conditions have proven to be high-strength carbons running against silicon carbide.

Offshore

Adverse environmental conditions, high rotational speed and pressure levels as well as corrosive media constituents place demanding requirements on sealing technology used in the offshore production and subsequent conveyance of oil and gas. Not only that but in many cases highly abrasive mixtures of crude oil, water, gas and sand cause a high degree of wear. MSE has proven itself with its heavy-duty mechanical seals with innovative and tailor made seal components with high-strength seal faces , guaranteeing longer service life even in highly stressed pumps.

Compressors

High speed machines whose trouble free availability constitutes a major precondition for many process engineering operations. Key criteria for the selection and design of compressors are the working medium, the compression ratio, the volume flow, the number of intermediate inputs & outputs and the design of the shaft seal which assumes critical importance.

Power

Sealing systems featuring maximum operational reliability, convenient maintenance and low leakage rates with necessary environmental protective measures are standard requirements in modern power stations. The product range includes mechanical seals and supply systems for auxiliary and secondary pumps, boiler circulation pumps and feedwater pumps as well as mechanical seals and carbon floating ring seals for turbines, compressors and fans.

Hot Water

Hot water is conveyed by pumps for a variety of purposes in thermal energy generating systems, district heating systems, home heating systems and so on. The suitability of a mechanical seal for such applications depends on many different parameters, e.g. pressure to be sealed, temperature at the seal, sliding velocity, power consumption, water quality etc.

Refinery

The processing of crude oil in refineries is a complex and multi-stage process in which crude oil is transformed into refined, high-quality end products or feed materials for petrochemical industry. Sealing technology for such diverse applications have to meet challenges in various respects; risk of insufficient lubrication and dry running, media with a diversity of physical properties, high and low temperature ranges and the handling of hazardous substances and all other conditions which need to be controlled with absolute reliability. With a comprehensive range of API-compliant quality seals and supply systems MSE is playing a key role towards ensuring the reliability and safety of refinery processes.

Waste Water

Municipal and Industrial sewage is conveyed by waste water pumps into collection tanks at the sewage works. Sewage works pumps are usually operated with single seals in either a dead-end arrangement (conical) seal chamber or with product circulation or external flushing (cylindrical seal chamber). While standard seals are in many cases adequate for applications involving the supply of fresh water or conveyance of waste water, special engineering solutions are a necessity where heavy-duty applications in the spheres of drinking water supply or seawater desalination plants are concerned. On the other hand, thermal energy provision requires individual account to be taken of parameters such as pressure, temperature, sliding velocity, friction, water quality and additives. Their high quality ensures that MSE seals significantly boost the availability of pumps in all types of water-related applications.

Mining & Mineral Processing

The cutter heads on quarrying and mining machines are fed with water, not only for cooling purposes but also for settling the dust and extinguishing any sparks produced by the cutting tools. Mechanical Seals perform the dual function of a rotary joint and a seal for the cutter and roller heads. Sealing systems used on these equipment are exposed to abrasive and chemically aggressive media. In some applications, high temperature and pressure make conditions even more challenging. Despite the harsh operating environment, users expect high reliability to avoid costly downtime.
