The model 87212 pump is a single-acting pump with a double-acting, hydraulic cylinder that requires a four-way valve and timer for operation. Hydraulic pressure powers the piston on the delivery stroke and returns it to priming position.
Depending on the type of reservoir used, the pump is suitable for both grease and oil applications. The 87212 pump requires a specially designed reservoir that must be ordered separately.
