These Special Order Zeta Series Three Diaphragm Poly Pumps are designed to withstand chlorine, abrasive materials, liquid fertilizers, de-icing materials, suspension products, pesticides, and other hard-to-handle fluids. The Udor Zeta-40P and Zeta-85P Poly Diaphragm Pumps are constructed of polypropylene and stainless steel liquid handling parts so that they are more resistant to chemicals and provide a longer pump life. The Zeta 40P/GR and Zeta 85P/GR-5 are fitted with a gearbox for 4 - 6.5 HP gas engines with 3/4" (19 mm) shafts. All models include a control unit.

Roof cleaning and roof protecting can lengthen the life of your roof. Algae, fungus or destructive moss can grow on your roof shingles, wood shakes, barrel tiles, concrete tiles, clay tiles or wooden decks and can cause permanent damage. The Zeta Poly Pumps have enough power to allow you to stay on the ground and spray your roof with water, roof cleaning chemicals or eco-friendly roof cleaning or protecting products. These Udor Pumps can be run with a gas engine coupled by a gearbox or straight from a tractor PTO allowing for more versatility. Popular with power washing, handyman home repairs, cleaning contractors, roof cleaners, property maintenance, home improvement companies, restoration, roof protecting and roof renewing.

These Zeta Polypropylene Diaphragm Pumps are not only suited for roof cleaning, they are also common in horticultural and agricultural spraying applications, mostly for lawn care, tree spraying, fluid transfer, dust suppression, cleaning, washdown, pest control, weed control, and more.
