Valve Balls on Air Operated Double Diaphragm Pumps
A diaphragm pump is driven by compressed air and uses reciprocating functions such as the valve seats and valve balls to pump the fluid. The design allows for self priming, large suction lift, and the ability to run dry without any damage to the pump. Both valve seats and valve balls are critical components for a proper function of an air operated double diaphragm pump.
Ball valves on Diaphragm pumps can be found in multiple industries like:
- Coating & Glue
- Food & Beverage
- Oil & Gas
- Printing & Painting
- Pulp & Paper
- Steel & Metal
Valve Balls come in a Variety of Materials
Every industry or solution has it own selection requirements if it comes to ball valve material. They come in a variety of materials (availability may vary per manufacturer) and designs to meet specific application needs such as chemical compatibility, temperature, abrasion resistance, and certification requirements.
Most common used materials supplied by Thinqk Pump Parts:
An excellent general purpose diaphragm for use in non-aggressive applications such as water-based slurries, well water or sea water. Exhibits excellent flex life and low cost.
Color Code: Green (common color) Pump manufacturers intent to use brand specific color
Excellent for applications involving petroleum/oil-based fluids such as leaded gasolines, fuel oils, non-synthetic hydraulic oils, kerosene, turpentines and motor oils.
Color Code: Red (common color) Pump manufacturers intent to use brand specific color
Excellent for use in applications requiring extremely cold temperatures. May also be used as a low cost alternative when pumping dilute acids or caustics
Color Code: Blue (common color) Pump manufacturers intent to use brand specific color
Excellent for use in applications requiring extremely hot temperatures. May also be used with aggressive fluids such as aromatic or chlorinated hydrocarbons and highly aggressive acids. Color Code: Silver or White (common color) Pump manufacturers intent to use brand specific color
Excellent choice as a low cost alternative to PTFE in many acidic and caustic applications such as sodium hydroxide, sulfuric or hydrochloric acids. Exhibits excellent abrasion resistance and durability at a cost comparable to neoprene
Color Code: Cream (common color) Pump manufacturers intent to use brand specific color
Exhibits excellent abrasion resistance, flex life and durability. This material is FDA approved for food processing applications. An outstanding general purpose diaphragm as well.
Color Code: Cream (common color) Some brand use alternative color
Excellent choice for applications requiring high oil resistance that meets or exceeds that of nitrile (Buna-N). This material exhibits exceptional performance for a variety of fluids
Color Code: Black (common color) Pump manufacturers intent to use brand specific color
Excellent choice when pumping highly aggressive fluids such as aromatic or chlorinated hydrocarbons, acids, caustics, ketones and acetates.
Color Code: white. (common color) Pump manufacturers intent to use brand specific color
Excellent chemical resistance and can be used for food processing applications because it’s easily cleaned and doesn’t corrode.
