Inquiry (采购产品): Antifreze injector pump Hi! I as many others I am sure have the need to inject antifreze into an ordinary domestic hot water heating system. Such systems typicaly have an accumulator pressurized to 12 to 60 psi with a rather inflexable rubber diafram and a host of presure limitations. In general it is necessary to partialy purge the system and pump 3 to 12 gallons of propolene glycol ot similar antifreze material from a can into the system against the accululator and the gravitational head of a two or three story building. Perhaps it is my ineptitude but I have not found a pump designed with that application in mind or a description which would indicate that the pump might be useful for the purpose described. If you have, know of or have relivent information I would appreciate it.
