Parts for Water Treatment Aeration Systems


Includes air pumps and air pump parts, installation kits, check valves, mounting shelves, pressure gauges, aeration tanks, aeration heads, and complete vent kits. Kits for air pump and solenoid repair. Parts on this page are compatible with the Aermaxsystems we sell but will interchange with parts from many water aeration systems.


This page features parts for high capacity, full-vent aeration systems. (It doesn't list venturi valves ("micronizers"), passive air vents, small aeration tanks or other parts used with low-cost aeration systems, but we can usually provide them if you call. )

For complete aeration systems, the Airhead pump control system, double aeration kit, and other aeration supplies, please see our main Aermax systems page.


Air Pumps

In general, the standard air pump handles treatment systems with service flow rates up to 15 gpm. Above 15 gpm, use the commercial-grade pump. All pumps include an air intake filter.

General Pump Information
Standard Air Pumps: AM101 & AM102
  • Weight: Around 8 lbs.
  • Water resistant (can be operated in a somewhat moist room atmosphere, but should not be used outdoors).
  • Withstand temperatures of 40 to 100 degrees F if there is not excessive moisture.
  • Noise Level: Approximately 50 decibels.
  • Life Expectancy: 20,000 to 25,000 hours before bearings need replacement.
  • Materials: Body and most parts are aluminum. Valves are stainless steel, and the compression cup is Teflon. Pumps have 16-gauge wire.
  • These pumps are not designed to inject fluids. Ozone can be used under certain conditions, but wet ozone will erode the aluminum pump body. Use with ozone will void the warranty.
  • Compression Technology Used: Rocking Piston with Induction (not commutator) motor.
  • Injection Output: 0.38 cfm @ 0 psi. 0.15 cfm @ 50 psi.
  • Maximum Pressure Output: 100 psi, but recommended maximum operating pressure is 70 psi.
  • Normal Air Pump Cycle: 5 to 10 psi of well pump setting. For example, if the well pump is set at 30-50 psi, the air pump might run at 30-35 psi.
  • Recommended Maintenance: Replace Teflon compression cup every 12,000 hours. Replace bearings every 20,000 to 25,000 hours. The motor is self-lubricating. Do not oil.

Air Pump Installation Kits

Includes pressure gauge, poly connectors, tubing, air regulator valve, check valve, and shelf.

Part # Description Price
AM004 Deluxe Installation Kit with Metal Shelf & Stainless Steel Check Valves. Kit includes ARV (Air regulator valve), 0-100 psi pressure gauge, poly connectors, and tubing. For use with standard air pump. $159.00

Aeration Tanks

Tank Sizing Rules: Gallon capacity of an aeration tank should be at least double the gpm flow rate. The standard 10" X 54" tank holds 16 gallons of water and handles flow rates up to 8 gpm. The standard 12" X 52" tank holds 22 gallons and handles flow rates up to 10 or 11 gpm. For hydrogen sulfide treatment, the standard 10" X 54" Aermax-style unit treats 6 to 7 ppm well. For up to 12 or 13 ppm, use a 12" X 52" tank.
