Lobe Pump OMAC

Omac is Italian manufacturer of lube pump. Standard Lobe Pumps in AISI 316 stainless steel are assembled on a cast iron gear box which has a protective coating in epoxy paint finish. The chamber separating the rotor case and gear box enables the fitting of balanced compact reversible mechanical seals, avoiding the contamination between the pumped fluid and the gearbox lubricant.

The base of the gearbox is designed to make installation easier for connecting into horizontal and vertical pipelines. The OMAC Lobe Pump is modular in design allowing the main parts such as the rotor and seals, to be change quickly and easily.

Special Version

Enlarged suction inlet

The B115, B220, B330, B440, B490 Models can be supplied with enlarged rectangular suction inlets allowing highly viscous products such as semisolid pastes or mixtures containing semi-solid pieces to be pumped.

In these cases the pump is generally positioned with the port on a vertical axis in order to allow the entry of the product under gravity directly beneath the hopper.


 

Aseptic Version

Internal pressure lelief valve

The pumps can be supplied on request with hygienic by-pass or pressure relief valves. This device protects the pump from pressure peaks or restrictions in the discharge and assures excess liquid deviation during CIP and SIP. The relief valve can be manually selected as a fl ow regulator in order to pass product allowing the pump to run continuously.

This valve can be incorporated in the end cover that replaces the standard cover, providing a pressure relief valve loop from discharge to the suction area; alternatively it can be incorporated in the discharge pipework, relieving excess pressure by by-passing product through a loop back to the suction side.

External pressure lelief valve

The integral relief valve is suitable for CIP process line and functions for either direction of fl ow: it is available on Models B100 to B490. On all models it is possible to assemble an external pressure relief valve in order to recycle the whole pumped product, this valve is especially suitable for frequently operations and for volatile, heat or shear sensitive product. For both of the valves a manual, pneumatic or automatic operation is available.


 

Mounting & Drives

MAC Rotary Lobe Pumps can be supplied either bareshaft or complete with baseplate in either stainless steel (AISI 304) or painted iron, couplings, guard and electric drives. It is also possible to have baseplates suitable for mounting the pump on when it has vertical connections. Trolleys and overhead bases and such accessories as adjustable feet and stainless steel shrouds covering the motors can also be supplied as to build pumping sets which exactly satisfy customers’ requirements.

Power transmission can be variable speed via a mechanical, hydraulic or belt adjustable speed unit; alternatively it can be fi xed speed via reduction geared motor. For controlling the pumps the options are various and these include on off reversing switch, inverter integrated into the motor, IP65 inverter, electric control panel with IP21 inverter for remote control signal.
