Neutrasafe NSP-50 neutralizing condensate pump has a guideline capacity of 500,000 BTU/h of appliance input. Our Neutra-pH media is contained in a sack in the serpentine neutralization chamber. The neutralization chamber has a clear easily removable cover for visual inspection and easy media replacement. Our patent pending base was designed and manufactured to hold the Little Giant VCMA-20ULS condensate pump that has been an industry standard for many years. Our base contains the pump chamber which is the same size as the standard VCMA20 pump. It also contains the neutralizing chamber. There is a separate inlet for the acidic condensate. From the inlet the condensate flows under the inlet gate, thru the serpentine neutralization chamber which contains the media sack and the over the outlet gate into the pump chamber. The original inlets in the VCMA pump are retained for use with non-condensing condensate such as A/C or dehumidification.
