Product Description

Provide your sprayer with the dependable performance it requires to remain active in the field for many years to come with this Annovi Reverberi AR70BP-SP Diaphragm Pump.

Capable of providing superlative performance on many small-to-medium sized sprayers, this low pressure diaphragm pump is equipped with two BlueFlex diaphragms and plastic-coated aluminum and stainless steel liquid handling parts for excellent chemical resistance.

This pump can be used for various agricultural spraying, lawn care, pest control, weed control, liquid fertilization, de-icing, and much more.

Some other features include a newly-designed diaphragm cut-out system that prevents contact tearing even in heavy-duty operating conditions, pistons with rings for a more efficient oil cushion system to protect diaphragms, and spherical sector profile valves for lower flow resistance and improved volumetric efficiency.
