*High speed operation: high measurement precisions, up to 360 strokes per minute which eliminate the pulsation effect.
*Compact size: small, quiet and stable operation
*Durable diaphragm: the diaphragm is made by PTFE, which is compatible with all kinds of chemicals. In typical use, the diaphragm can last up to five years, which 5 times as national standard GB/T7782-2008
*Strong stability: working stability in AC 100-240V, and suitable for the range of 50-60Hz
* High protection level: protection level reached to IP65, it allowed pump to provide safe services at severe operaton condition
*Ball check valves: it through double valve ball, seat and sleeve to form the sealing system, that enhance the precision
*Several types: manual control or automatic control, the automatic control can divided to: 4-20mA electric current signal control, digital impulse signal feedback control, digital impulse feedback control with Rs485 communication interface, 4-20mA electric current signal control with Rs485 communication interface.
*Percentage adjustment: local adjust percentage for stroke and frequency 0~100%
*Level monitor, low-level shutoff with alarm output

Two misunderstandings of powder pesticide use
Powder pesticides are easy to store and not volatile, which makes them a popular choice among many vegetable farmers in agricultural production. However, there are two common misconceptions when using these products.
Myth 1: All powder pesticides are used with water. In reality, powder pesticides are made by mixing one or more active ingredients with clay or other fillers, then mechanically grinding and blending them. These powders are coarse, have good flowability and dispersibility, but they are not easily wetted by water and cannot be suspended in it. Therefore, they are not suitable for spraying with water. Instead, they are typically used for dusting, or mixed with seeds, soil, or bait for specific applications.
Myth 2: Wettable powders can be sprayed as dry powder. This is incorrect. Wettable powders are formulated with pesticide ingredients, fillers, and wetting agents, allowing them to mix well with water and form a stable suspension. They have better fineness than regular powders and are designed for foliar application. However, they should not be applied as dry powder because they contain moisture-absorbing substances that can cause clumping. Additionally, they are not recommended for soil treatment or seed dressing due to their high concentration and poor dispersion properties, which may lead to plant damage.
It’s important to understand the correct usage of different pesticide formulations to ensure effectiveness and safety.

Always follow the manufacturer's instructions and local regulations to protect both crops and the environment.
