Product Description

How it Works?

Separation takes place in a solidsretaining, also known as a solid-wall, bowl that can be arranged for purification or clarification (optional). In both cases the contaminated oil is fed to the separator by a feed pump through the oil inlet and is separated by centrifugal force into its various phases. The heaviest phase, sludge, is forced to and deposited at the periphery of the bowl. Separated sludge is collected in the space at the periphery of the bowl and removed periodically by hand using the stainless steel sludge basket.

The clean oil is continuously discharged by the built-in paring disc pump. Water leaves the bowl via an open outlet. When operated in purifier mode, a gravity disc must be fitted to obtain the correct interface position (the boundary between the separated oil and the water seal) in the separator bowl. In the optional clarifier mode, a clarifier disc is fitted instead of a gravity disc. A MAWA-40 water seal alarm is available as optional equipment to monitor the pressure in the clean oil outlet. The control unit will shut off the oil feed to the separator in case a pressure drop is detected and give an audible and visible alarm.

Each MMB separation system comprises:

1)An MMB separator

2) Ancillary equipment consisting of connections and valve assembly

Optional equipment:-

1) Independent oil feed pump

2) Oil heating system, steam or electric

3) Water seal alarm MAWA-40

Features and benefits:-

1)Compact, robust design

2) Internal paring disc for discharge of clean oil

3) Large sludge space Belt-driven

The major benefits are:

1) Easy to install.

2) Requires limited space.

3) Pressurized discharge of clean oil.

4) No need for downstream pump.

5) Fewer service man hours.

6) Larger sludge space extends operating period between manual cleaning.

7) Lower maintenance and spare parts costs.
