Description

The Comet P 40/20 AENP is a professional-grade, medium-pressure diaphragm pump engineered specifically for the application of aggressive chemicals, acids, and fertilizers. Part of the “Poly” series, it is widely considered a staple in the soft wash industry due to its corrosion-resistant construction and reliable flow rate.

Technical Specifications

Key Features & Designations

• AENP Designation: This specific suffix indicates that the pump is built with polypropylene and stainless steel components in the fluid path. This makes it highly resistant to corrosive soft wash chemicals like sodium hypochlorite (bleach).

• Viton Diaphragms: Unlike standard NBR (Buna) diaphragms, Viton is specifically chosen for its ability to withstand acids and harsh chemical solutions without swelling or degrading.

• Aluminum Head Plates: To prevent the polypropylene heads from “flexing” under pressure, Comet uses external aluminum plates to maintain structural rigidity and seal integrity.

• RID / 6F Version: This configuration typically refers to the 6-hole flange hitch used for mounting the pump to tractor PTOs or universal drive systems.

• Molded One-Piece Collector: Designed to minimize leak points and streamline the plumbing within the pump head.

Ideal Applications

• Soft Washing: The primary choice for professional roof and exterior cleaning, effectively handling bleach-based solutions to kill mold, algae, and mildew.

• Agricultural Spraying: Used for applying herbicides, pesticides, and liquid fertilizers on small to medium-sized crops.

• Industrial Chemical Transfer: Suitable for moving water-soluble detergents, paints, and de-icing fluids.

• Pest Control: Reliable for high-volume perimeter spraying and lawn treatments.

Maintenance & Service Kits

Regular maintenance is vital for diaphragm pumps, especially when handling corrosive fluids. Always flush the pump with fresh water after every use.

• Diaphragm Kit (Viton): 5026.0350.00 (Standard Viton kit for 3 diaphragms)

• Valve Kit: 5025.0021.00

• Oil Type: Use SAE 30 non-detergent oil or Comet Pump Oil.

• Oil Level: The metal oil cup features a visible level; the oil should always be visible in the sight glass to ensure the mechanical drive remains lubricated.
