The V-7 Series is a mini pump designed for lighter metering applications and minimal maintenance. The pump end of the unit utilizes a precision inline machined casting insuring exact alignment of the drive mechanism and the piston head assembly, minimizing wear. The pump is driven by a low horsepower gear motor which is available in several ratios for the required stroking rate. The wet end of the pump is precision machined and utilizes a ground stainless steel piston to minimize packing wear. The output of the pump is varied from zero to maximum by manually adjusting the piston stroke length.
It is ideal for use in low pressure applications where a controlled volume of chemical treatment is required.
