Series LZ Slow running Gear Pumps

for thick liquids
Type LZ 80 and LZ 120

Slow running gear pumps are suitable for thick Liquids with a for delivering certain degree of lubricity. The material must not contain any hard substances. The driving shaft is sealed driving shaft with a graphit gland. Radial or axial force can not be picked up by the shaft. The sense of rotation is either right or left. The shaft is running in friction bearings. The housing is made of GG25. The cog-wheels and shafts are made of hardened and grounded steel.
