vacorex VX

Product catalog summary

Introduction
The vacorex6 is a gear pump introduced by MAAG, designed for modern polymer production processes. It is capable of discharging at high pressure even under low fill levels and high vacuum conditions. The pump is suitable for a wide range of polymer grades without compromising quality, offering reliability, low maintenance, and robustness.

Benefits

Up to 40% more throughput or 28% more pressure compared to classic pumps of the same size.
30% better heat transfer in bearings.
15% larger inlet with optimized geometry.
8% better volumetric efficiency.
10% less energy consumption.

Pumping Media
The vacorex6 can handle various media including PET, PBT, Polyamide, Polycarbonate, and others such as Silicone, Oil additives, and Elastomers.

Pump Types

ST: Compact with threaded hole at inlet flange.
LT: Optimized NPSH with threaded hole at inlet flange.
LB: Optimized NPSH with through boring at inlet flange.
MR: Retrofit for Gen. M with threaded hole at inlet flange.
5R: Retrofit for Gen. 5 with through boring at inlet flange.

Accessories
High-precision monitoring systems for pressure and temperature are available.

Model Range
The vacorex6 is available in three models: GU, EV, and EP, with varying discharge pressures and capacities. The discharge pressure ranges from 210 to 330 bar, and the capacity varies depending on the specific volume and pump size.
