Udor Diaphragm Pumps
We are firm believers in the reliability, ease of maintanance and overall design of Udor Kappa and Beta series diaphragm pumps. The gentle wave action generated within these pumps is not aggressive enough to harm the biology contained in compost teas, particularly at pressures below 150 pounds per square inch (psi). All units are suitable for conventional use with no modifications in any way.

These diaphragm pumps come complete with pressure regulators (control units) and gear reduction units ready to be installed and put to work.
