Alldos Dosing Pump PartsAlldos 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 select parts for old Alldos dosing pumps are available through The Panner Company. Maintenance kits typically include a pump head gasket, diaphragm and the suction and discharge check valves.  For valves larger than DN20 size, the manufacturer normally provides the valve inner components only. Individual electronic or drive component parts for Alldos pumps are difficult to identify and order at this stage. If a service kit cannot complete your repair, it may be time to upgrade to a new pump.

In order to quote service kits or parts we will either need a part number or the complete model number of the pump. For example, a typical complete model number for a Model M221 Alldos pump would be "M221-14 D00R06A50V07P03". If the pump is of later vintage, a typical part number from Grundfos would be an 8 digit number like: "91835070".
