Binks Pressure Pots & Tanks: A Comprehensive Guide

Binks’ Pressure Feed Tanks (SYNO: Pressure Pots) are commonly used in industrial spray painting operations and are responsible for holding and pressurizing the paint or coating material to ensure a consistent and accurate application to the intended surface. In this article we will provide a comprehensive overview of the Binks pressure pot range, including features, key considerations when buying, FAQs, a Binks model description chart and a Binks model overview.

Features of Binks Pressure Feed Tanks

Binks pressure feed tanks are designed with several key features that make them the ideal choice for industrial spray painting applications. Some of these features are:

  • High Pressure Capability: The tanks are capable of pressurizing coating material up to 110 psi [7.5 bar], allowing for a precise and consistent application of even high-viscosity materials to the intended surface.
  • Options: Binks pressure feed tanks are available in a variety of tank sizes (from 2 to 60 gallons or 7.6 to 227 liters), tank materials (from zinc-coated and galvanized to fully stainless steel), and options for regulation and agitation. In fact, Binks oofers the widest range of pressure tank options in the industry.
  • Regulatory compliance: Tanks fully comply with global pressure regulations, including PED, ATEX, ASME, CE
  • Heavy-duty construction: Binks pressure tanks are constructed from heavy gauge steel with forged steel clamps. This ensures that with proper maintenance they will last for many years.
  • Easy to clean: Binks pressure feed tanks are designed with smooth surfaces, making them easy to clean and maintain. Disposable tank liners are also available.

How to choose a Binks Pressure Tank/Pot?

There are four (4) key considerations when purchasing a Binks Pressure Feed Tank.

Step 1 Select Tank Size

It is important to ensure that the correct size tank is selected for the spray application. Binks pressure tanks are available in 2, 5, 10, 15, 30 and 60 gallon sizes. As a rule of thumb, you can take the amount of coating material that will be sprayed during an 8 hour shift and then choose the next available pressure tank size. For example: If approximately 12 gallons of coating (single component) is sprayed per 8 hour shift, then the 15 gallon tank would be a good choice. This rule applies to regular single component coatings. If a fast curing plural component coating is used, the tank life of the coating must be considered.

Step 2: Select Tank Material

Are water-based or solvent-based coatings used? What level of corrosion resistance is required?
A tank should be selected that is constructed of materials that can withstand specific properties of the coating material, e.g. whether solvent or water based, aggressive acid materials, etc. It should also be ensured that the tank does not exceed the maximum pressure level of the application. Binks pressure tanks are available in the following materials (and maximum pressure ratings)

  • Zinc Plated (80 psi/5.5 bar)
    Good general corrosion resistance, but not suitable for water-based coatings
  • Zinc Plated with Stainless Steel Lid and ST ST Fluid Passages (80 psi/5.5 bar)
    Better overall corrosion resistance, compatible with water-based coatings when liners are used
  • Galvanized Carbon Steel (110 psi/7.5 bar)
    Better overall corrosion resistance, but not compatible with water-based coatings
  • Fully Stainless Steel – Electropolished (110 psi/7.5 bar)
    Best overall corrosion resistance, suitable for most materials including water based

Step 3: Select the Number of Regulators

Binks tanks are available with no pressure regulation, single regulation and double regulation. Extra sensitive pressure regulators are available as an option for improved low pressure control.

Step 4: Select Agitator Options

Coatings that remain well dispersed over time may not require agitation. However, if the material requires constant agitation, a direct drive agitator (low viscosity material, small volume) is an option. For higher viscosity materials and larger volumes, gear-reduced agitators with lower speed and higher torque are recommended. Reduced gear drives are also good if there is a risk of air entrainment. Most Binks pressure tank models are available without agitator, direct drive or gear drive (15:1 ratio). All drives are air operated.

  • Direct Drive: 1/2 hp air motor, three blade propeller (for low viscosity/small volume)
  • Gear Drive (Rotary): 1/2 hp air motor, 1:15 gear ratio, recommended speed: 60-80 RPM (for higher viscosity/larger volume/risk of air entrapment)
  • Gear Drive (Oscillating): 180′ reciprocating action, provides very good agitation of water based shear sensitive materials, low air consumption.

FAQ – Frequently Asked Questions

  • What are ASME Code Tanks?
    ASME code or ASME coded pressure tanks are built according to the manufacturing standards of the American Society of Manufacturing Engineers (ASME).
  • Which spray guns can be used with a Binks pressure pot?
    Binks pressure pots can be used with ‘pressure feed’ spray guns from a variety of manufacturers. Important: The spray gun must be able to withstand the maximum pressure of the pressure pot and be fitted with a suitable air cap for pressure feed applications.
  • What are the actual capacities of the Binks pressure tanks?
    It can be a little confusing when it comes to the size and designation of the Binks pressure tanks, as some brochures or manuals refer to the 2.8 gallon tank, for example, and some refer to the 2 gallon pressure tank, while both refer to the same model. The size designation and actual capacities for the 83 and 183 models listed below are as follows:
    2-gallon models actually hold 2.8 gallons
    5-gallon models actually hold 9.8 gallons (or one 5-gallon pail)
    10-gallon models actually hold 11.8 gallon
    15-gallon models actually hold 19.8 gallons
