PLGP 2500/PW2

1- FRONT COVER 

The lobes and wear plates can be easily replaced by simply removing the front cover, without having to dismantle the pump housing or piping.

The front cover is supplied in CAST IRON material.

2- WEAR PLATE

Internal removable abrasion resistant steel.

3- LOBES

Externally vulcanised rubber on a cast iron core, in a wide range of elastomers (NBR, HNBR, EDPM, FPM and others on request).

The geometry of the straight 3-wing allows a suction capacity of up to 7-8 metres.

4- PUMP HOUSING

Different types of process connections are available according to international standards (EN, DIN, ANSI and others) or in special designs.

The pump housing is supplied in cast iron material.

5- SHAFT SEALS 

Mechanical seal with conical rings: easy assembly and disassembly and very small footprint (no measurements are required as the seal is loaded with the pump assembly). Ceramic or tungsten carbide materials. Self-lubrication in an oil bath, which also allows dry running of the pump chamber for short periods.

6- GEAR BOX 

Synchronised precision gears with a 1:1 ratio allow concentric counter-rotation of the lobes. Pairs of high-strength tapered roller bearings. Depending on the version, there is the option of having a separation chamber between the pump compartment and the gearbox, eliminating the possibility of any product contamination and allowing constant lubrication of the mechanical seals.
