 Overview
With our diverse standard and high performance pumps we are able to serve
all your needs and response to any challenge.
Our rotative displacement pumps are robust, self-priming and have running
dry capability.
On demand, we provide as well pumps which are API, ATEX and TA Luft
compliant

ADVANTAGES
& HIGHLIGHTS
Zeilfelder rotary lobe pumps are specially designed for*:
- complex and difficult challenges
- liquids containing up to 90% of solids
- liquids containing shear sensitive
materials (for example fruits)
- polymerizing or coagulating liquids
- liquids containing cristals or fibers
- dosing (repeat accuracy > 99 %)
- pressure up to 64 bar
- suction heights up to 8 m
- flow rates from 0.03 to 28.500 l/min.
- viscosity from 0.3 to 1.4 mPas
- temperature from -60°C to 450°C
- explosive und toxic substance
Avantages*:
- Pumps out of all possible materials
- high durability through high-end bearings and special coatings
- low energy consumption and high efficiency up to h = 92 % through:
- lowest manufacturing tolerance
- special design
- interchangeable thrust segments (axial bearings)
- dry running capability
- low pulsation characteristics (rotary wing pumps)
- higher displacement/revolution
- lower rotation speed
- gentle pumping
- revolution speed adapted to medium
- non-destructive pumping holding clipping under 5%
- dual rotation direction
- reduced noise level
- no valves
Optional:
- packing glands
- simple acting mechanical seal
- double acting mechanical seal
- explosion proof
- heating jacket (for water, steam or heating oil)
- minimal surface roughness down to 4µ through electropolishing
- API, ATEX and TA Luft compliant
