Technical Specification: Chemical Resistance & Material Selection

To meet the rigorous demands of industrial and laboratory environments, the PYSP370-XA is engineered with high-performance elastomers and polymers. We offer customizable sealing options based on the specific chemical properties of your fluid:

1. Sealing & Diaphragm Material Options

Depending on your application, the internal seals and diaphragm can be configured with:

EPDM (Ethylene Propylene Diene Monomer): The standard choice for general acid and alkali resistance. It excels in handling polar solvents, water-based solutions, and dilute acids/alkalis.
Viton (FKM): Recommended for applications involving aggressive chemicals, oils, or fuels. It offers superior thermal stability and broader chemical compatibility.
PTFE (Teflon) Components: For the most demanding environments, we use PTFE-coated components to ensure zero-leakage and high durability against strong oxidizers.

2. Chemical Compatibility List

The PYSP370-XA (Acid and Alkali Resistant version) is tested to handle a wide range of corrosive fluids, including but not limited to:

Acids: Dilute Sulfuric Acid (H2SO4), Hydrochloric Acid (HCl), Acetic Acid, and Phosphoric Acid.
Alkalis: Sodium Hydroxide (NaOH), Potassium Hydroxide (KOH), and Ammonia solutions.
Cleaning Agents: Bleach (Sodium Hypochlorite), detergents, and hydrogen peroxide solutions.
Lab Reagents: Buffered solutions and pH-adjustment chemicals.

Engineer's Note: While the 370 motor pump is highly resistant, chemical compatibility can be affected by concentration and temperature. For concentrations exceeding 10% or temperatures above 50°C, please contact our technical team for a dedicated material compatibility test.

Next:

1. What materials are used in the PYSP370-XA to ensure acid and alkali resistance?

Answer: The PYSP370-XA features a specialized diaphragm and valve system made from high-grade EPDM or Viton (customizable). The pump body uses corrosion-resistant engineering plastics, making it ideal for transporting weak acids, alkalis, and chemical detergents without degradation.

2. Can the PYSP370-XA pump operate continuously for long periods?

Answer: This 370 motor pump is designed for intermittent use but can support extended cycles with proper heat dissipation. Its typical lifespan exceeds 10,000 cycles (on/off test). For 24/7 continuous operation, we recommend consulting our engineers to optimize voltage and cooling for your specific environment.

3. Is the PYSP370-XA micro pump food-grade certified for medical or food applications?

Answer: Yes, we offer food-grade versions of the PYSP370-XA. We use FDA-compliant materials for all internal components that come into contact with liquid. It is widely used in coffee machines, water dispensers, and medical diagnostic equipment requiring high hygiene standards.

4. What is the maximum suction lift and head pressure for this model?

Answer: The PYSP370-XA provides a self-priming suction lift of up to 0.5 meters and a vertical discharge head of over 0.5 meters. Performance varies slightly depending on whether it is configured for 6V or 12V. Detailed PQ curves (Pressure vs. Flow) are available for download in our datasheet.

5. How can I control the flow rate of the PYSP370-XA 370 motor pump?

Answer: You can easily control the flow rate by adjusting the input voltage (between 3V and 12V) or by using a Pulse Width Modulation (PWM) controller. Lowering the voltage reduces the flow and noise, while a PWM signal allows for precise digital control in automated systems.
