The Zeta 85 Diaphragm Pump is a heavy duty pump with plasticized aluminum heads and glass-filled nylon manifolds, while the Zeta 85P Poly Pump is ideal for salt water with its polypropylene and stainless steel liquid handling parts, as well as chemically resistant diaphragms designed for a long life. The difference between the Zeta 85 and 85P is the polypropylene and stainless steel liquid handling parts on the Zeta 85P.

Both the Udor Zeta 85 and Zeta 85P Diaphragm Pumps are commonly used to clean roof tops. Hot and humid weather can lead to mold, mildew and fungus forming on your shingled / tiled roof.
