The compact, easily useable metering pump results from a structure including a housing (20) with a pumping chamber (34) within the housing (20). A diaphragm (36) is located in the pumping chamber (34). An inlet includes a check valve (50) for allowing fluid to flow to one side of the diaphragm (36) but not the reverse and an outlet including a check valve (56) allows fluid to flow from the pumping chamber (34) but not into it. A pneumatically operated hydraulic pump (16) is located in the housing (20) and cycles the diaphragm (36).
