Chemical Metering Pumps
The Alldos dosing pump line was purchased by Grundfos Corporation in 2006. Alldos pumps were renamed and incorporated into the Grundfos offerings. Duplicates of older Alldos pumps are no longer available but maintenance kits and component parts for old Alldos dosing pumps are available through Panner Sales.
Positive Displacement (PD) pumps create pulsation and hydraulic shock due to the reciprocating nature of their stroking action, potentially damaging the entire pumping system.
A metering pump is not the only component of a chemical pumping system. Griffco is a manufacturer of components to help calibrate your pump, hold a constant pressure in the pipe and prevent siphoning.
