Disa pneumatic blast pot: reduced abrasive consumption, increased productivity, lower clean-up costs.
Disa pneumatic continuous pressure blast pot is controlled by components such as PLC, level gauge and differential pressure gauge. It can realize the functions of automatic shot feeding and continuous shot blasting without stopping the blasting process to refill the pressure tank with abrasives. This ensures the continuity and effectiveness of shot peening strengthening work, and meets the requirements of automated assembly line operations.
Features and benefits of Disa pneumatic sandblasting pot:
- Precise Abrasive Flow Metering
- Significantly Reduces Abrasive Consumption
- Easy Disassembly & Serviceability
- Wear Parts are Individually Replaceable
- Exceptional Wear Resistance
- Suitable for Multi-Outlet Applications
- Simultaneously Shuts Off Abrasive Supply to Blast Hose & Seals Pressure Pot
- Compatible with Pneumatic Safety Control Valves - Ensures Fast Response
- Easily Integrates into Most Existing Blast Systems
- Clean-Out Port: Clear blockages without valve removal from blast pot.
The blast pot is designed to be swiftly deactivated, thus ensuring enhanced safety.
To put the blast pot into operation, the Bleed valve must be closed by applying control pressure to the membrane. The air valve is open if we have no control pressure on the membrane, in other words, we speak here of a normally open air valve.
The compressed air enters the vessel through the main air valve through the riser pipe. The filling cone SP-014 is pressed upwards into the rubber collar ring by this compressed air flow. The blast pot now forms a closed vessel and is presurised
To start up the blast pot, open the main air valve by applying pilot pressure below the piston. The air valve is closed if we have no control pressure below the piston, in other words, we speak here of a normally closed air valve.
With the aid of the grit cylinder it is possible to have a set amount of blasting media dispensed through the grit valve housing. In the grit valve housing there is a spring which in the rest position always ensures that the piston rod with the rubber cone on it, starts in its outward stroke. In this rest position, the blasting medium flow in the grit tap housing is closed.
Product details
The abrasive blast pot is mounted directly beneath the abrasive storage hopper for gravity-fed operation. The covered hopper lifting tube assembly filters abrasives through the perforated baffle plate and effectively contains abrasive spillage during pot de-pressurization, preventing buildup in the work area.

1.Lower pot bracket: Bears the weight of the entire tank body, welded by section steel.
2.KL Valve Assembly (see figure)
3.600 Tank Body: Main cylinder for shot blasting, with a volume of 0.1 m³.
4.RF Admittance Level Gauge: Detects the lower limit of shot remaining in the tank. When the shot reserve is insufficient, the level gauge sends a signal to the PLC, which then initiates the shot feeding program.
5.Pneumatic Pinch Valve: Automatically controls valve opening and closing, with excellent sealing performance when closed.
6.400 Tank Body: Shot feeding tank for shot blasting, with a volume of 0.06 m³.
7.Rotary Paddle Level Switch: When the shot volume in the 400 tank reaches the sufficient level, the level switch sends a signal to the PLC, which then stops the shot feeding program.
8.Analog Pressure Gauge: Displays the real-time pressure in the tank or pipeline.
10.Safety Valve: When the real-time pressure in the tank or pipeline exceeds the designed maximum pressure, the safety valve opens to forcibly discharge air and relieve pressure, so as to ensure the safety of personnel and equipment.
11.Pneumatic Pinch Valve: Automatically controls valve opening and closing, with excellent sealing performance when closed.
12.Exhaust Valve: Pneumatically controlled, also known as pneumatic exhaust valve; mainly used to discharge compressed air from the shot blasting tank. This valve is interlocked with the air intake valve.

The pneumatic air intake valve is pneumatically controlled, also referred to as a pneumatic air intake valve; it is mainly used to deliver compressed air into the shot blasting tank. This valve is interlocked with the exhaust valve. The pressure supplement valve has the same function as the air intake valve, and its main role is to deliver compressed air to the shot blasting pipeline. Its structure is shown in the figure below.

Pressure Regulation of This Device: For pressure control, the ITV-type electro-pneumatic regulator and large-flow pressure reducing valve produced by SMC (Japan) are adopted to realize digital control of shot blasting pressure (with an error margin of less than ±2%).
Disa blasting pots
