Engineering solutions provider Bearing Man Group (BMG) launched engineering products manufacturer and supplier Omsa’s L-shaped 920 ℓ tank, at the end of 2013.

Through BMG’s acquisition of Omsa in 2012, BMG’s Fluid Power division has secured several filtration products, making it more competitive.

One such product is Omsa’s modular tank, which allows different grades of oil to be dispensed in a combined modular storage system and is suitable for several industries, including the chemicals industry. It is sealed to prevent any contamination of lubricant oil, and can be assembled to exact requirements and installed on surface or underground applications.

The design consists of an electric motor and a submersible pump, with a dual head filter unit, complete with six micron absolute rated spin-on filters. Oil is dispensed through a hose reel with a metered nozzle, for various mining or industrial equipment requirements.

The control operating principle of the L-shaped tank differs from previous designs, as pressure sensors allow a continuous variable control with digital capabilities. A single sensor safely controls the oil’s high and low levels in the tank, while system control measures are controlled by the programmable logic controller (PLC) and displayed on the colour touchscreen human machine interface (HMI).

Temperature can be controlled by a PT100 sensor, emitting an analogue signal and can also be controlled by the HMI.

The PLC is equipped with an Ethernet unit, allowing external communication and remote access to the PLC.

A particle counter monitors the condition of the filtered product. Cleanliness results of ISO 12/10/8 were achieved from this system and are in accordance with ISO 4406 standards. The industry standard is generally 18/16/14 – therefore, with this filtration solution, clean oil is guaranteed, says BMG.

Filtration on Wheels
Meanwhile, development on the Omsa mobile diesel filtration trailer was completed in May last year, in conjunction with the recommendations and requirements of a leading South African petroleum and oil company, BMG notes.

This system, which is used extensively in transport, earthmoving, construction, agriculture and mining applications, was designed by Omsa bulk fuel filtration product manager Philip Craig.

These mobile diesel filtration trailers remove particulate and water ingress – the most destructive contaminants in light and heavy vehicle diesel engines. Bulk fuel filtration systems ensure cleaner fuel to meet the finer tolerances on modern diesel injection systems.

Equipment failure is often attributed to excessive dirt and water ingress during the transport of diesel through the supply chain, which results in high maintenance costs and unnecessary downtime in production and transport.

Omsa’s mobile diesel filtration trailers consist of a basket strainer and prefilter, as well as a water coalescer and separator, gearbox, vane pump and an inline mechanical meter. Omsa’s filtration systems, if correctly maintained, guarantee extended operating life.

Secured Contracts
BMG’s bulk fuel filtration division contracted Omsa to design and manufacture filtration systems for two copper mines in Zambia, as part of the mines’ upgrade and expansion programme, which is currently in progress.

The life span of these mines has been extended by an estimated 16 years each, after exploration showed additional proven mineral reserves.

This filtration project, which was also secured in May, encompasses offloading, transferring and dispensing filtration systems for diesel and lubrication oils. Included in the contract are mobile drum trolleys, waste oil trolleys, closed loop sampling tanks, lubricant oil storage tanks and hose reel stands, all of which are within Omsa’s scope of supply and product range.

A leading global petroleum and oil company will supply fuel and lubricants in bulk directly to the transporter at various mine sites in Zambia. It is imperative to have cleaner fuel on the mine to reduce downtime and maintenance costs, also ensuring compliance with emissions controls.
