Recommendations for imported gear pumps
Thread Content
Our factory wants to use gear pumps to drip in the monomers for acrylic resin raw materials. I know that some reputable brands abroad include Viking and Tuthill; there seems to be another brand of similar repute, but I can’t remember it right now. Please help me think of it.
Is it necessary to use a gear pump? There are piston rotary pump types whose performance in all aspects is better than that of gear pumps!
Imported well-known gear pumps: Viking, Roton, Tuthill, Johnson.
We used a Roton as the compressor oil pump, and there was a lot of oil leakage – it was a real headache. The manufacturer wasn’t able to solve the problem either
The gear pumps from ALBIN in France are also good, but it’s best to use ALBIN’s industrial hose pumps for the resin material.
If you are worried about oil leakage, you can use a magnetically coupled triple-screw pump!
Swiss Mag and Japanese Shimadzu are both leaders in the field of external gear pumps
The Mag from Switzerland is a very powerful gear pump, capable of achieving pressures of up to 250 bar and transporting fluids with viscosities of up to 4,000,000 cp. Too much resin was used. It is recommended to consider using a Mag pump only if the outlet pressure exceeds 20 bar. Because VIKING, rotan, Tuthill, and Mag are not in the same category.
Thank you all. Our viscosity and outlet pressure are not high, so we will consider it carefully
We mainly use it for drip feeding, requiring a relatively steady flow rate, with a drip precision of 0.5 kg/min
