Diaphragm Powder Pump

1. SANDPIPER Powder Pump:
The SANDPIPER powder pump from the United States is a pump product used for transporting solid powder materials. The pump injects gas (air or nitrogen) at a certain pressure into the chamber during each discharge stroke, keeping the solid powder in a semi-fluid state. Driven by the diaphragm, the powder mixed with gas is expelled from the chamber and transported over a short distance through pipes.
The SANDPIPER powder pump adopts a new gas path induction distribution technology, achieving separation of the pneumatic motor's gas supply and the powder fluidization gas path. The fluidization gas pressure can be set according to the flowability of the powder (1.5-5.5 bar). For powders with low bulk density and good flowability, a lower fluidization gas pressure can be set to save energy and reduce the load on the air release component. The pneumatic motor's gas supply pressure can be set according to the delivery volume (2.0-3.8 bar).
The SANDPIPER powder pump is currently one of the products with relatively low energy consumption in its category, mainly due to its advanced main valve design and precision manufacturing process. The SANDPIPER team continuously optimizes and innovates to meet various application needs, combined with world-class professional design advantages, allowing our products to meet more application fields. The use of this product has certain requirements for the powder and the conveying process, and we cannot apply it blindly. In addition to existing mature application processes, other suggestions should be consulted with our technical department, and the material performance survey form should be filled out carefully. If conditions permit, we also welcome material testing. We are equipped with complete experimental facilities. Over the past decade, we have accumulated a lot of application data and experience.
2. Features and Applications:
a. Extremely convenient installation, compact size, the pump's discharge port can be connected to the inlet of other equipment with a flexible hose (or a rigid pipe). The pump's feed port can self-suction powder, outputting in a slightly positive pressure state, entering a closed device, with a small amount of gas discharged through the air release component;
b. Avoids dust flying around the production workshop, reducing air pollution and raw material waste;
c. Powder materials are transported in a closed management system, minimizing contact between operators and the powder;
d. The system is economical, simple to install and use, unlike expensive traditional large and complex pneumatic and mechanical conveying systems;
e. Lightweight, can be easily moved and used anywhere (can be installed on a small cart). Ready to use, no installation or debugging required;
f. Speed is adjustable. The pump's operating frequency can be adjusted by the intake pressure to meet the powder addition requirements of different sections;
g. The newly developed flap valve powder pump can transport powders with slight fibers or small solid particles.
