The One-Nut doube diaphragm pumps from Flotronic Pumps, so-called because they are held together with one nut on the opposite side of the pump from the external air valve, are now said to last even longer.
The original diaphragm pumps were enduring as they allowed fluid to pass between the diaphragms directly through the pump centre with air pressure operating on the outside. Now a revised diaphragm shape, which results in less stress, means the pumps are even longer lasting.
In other news, the company has updated its website which now features a special section that supports customers looking for authentic Flotronic replacement parts.
