Our Pumps
Hydrocarbon Solvents (e.g., gasoline, diesel, toluene, xylene)
-
Challenges:
Highly flammable and explosive vapors, low viscosity, leading to leakage risks can cause seal degradation in pumps
-
Safe Pumping Method:
Use explosion-proof pumps (ATEX-rated or UL-listed). Use seal-less magnetic drive pumps to prevent leaks. Grounding and bonding to prevent static electricity Vapor recovery systems to minimize fumes
Chlorinated Solvents (e.g., methylene chloride, trichloroethylene, perchloroethylene)
-
Challenges:
Highly corrosive to pump seals and gaskets. Heavier than water, causing handling difficulties. Toxic vapors require careful containment
-
Safe Pumping Method:
Use stainless steel or Teflon-lined pumps. Avoid elastomers that degrade in chlorinated solvents. Implement a closed-loop system to contain vapors. Ketones & Esters (e.g., acetone, MEK, ethyl acetate, butyl acetate)
-
Challenges:
Highly volatile and evaporate quickly. Can attack common elastomer seals (e.g., Buna-N). Can create explosive vapor-air mixtures
-
Safe Pumping Method:
Use Teflon (PTFE) Yamada diaphragm pumps or stainless steel. Ensure pumps are non-sparking (e.g., air-operated Yamada diaphragm pumps). Avoid open containers and minimize exposure.
Alcohols (e.g., ethanol, methanol, isopropanol)
-
Challenges:
Flammable with a wide explosive range. Can degrade certain pump materials (e.g., natural rubber).
-
Safe Pumping Method:
Use diaphragm pumps for containment. Ensure proper grounding and bonding. Use non-reactive materials like stainless steel or PTFE. Aromatic Solvents (e.g., benzene and styrene).
-
Challenges:
Carcinogenic and toxic; requires careful handling. Reacts with some elastomers, causing degradation. Can dissolve certain plastic pump components.
-
Safe Pumping Method:
Use PTFE-lined or stainless-steel pumps. Ensure adequate ventilation and closed-loop handling. Use double mechanical seals for leak prevention. Ethers (e.g., diethyl ether, THF - tetrahydrofuran).
-
Challenges:
Extremely flammable and volatile. Can form explosive peroxides over time. Can degrade plastic and rubber pump parts.
-
Safe Pumping Method:
Use air-operated Yamada diaphragm or peristaltic pumps. Monitor for peroxide formation and use stabilizers. Store in dark, cool, and oxygen-free environments. Amine-Based Solvents (e.g., ethanolamine, triethanolamine).
-
Challenges:
Corrosive to metals. Reacts with CO₂ in air to form deposits. High viscosity can create pumping resistance.
-
Safe Pumping Method:
Use gear pumps or Yamada diaphragm pumps. Ensure corrosion-resistant materials (e.g., Hastelloy, PTFE). Use heated pumps if necessary for viscous amines. Acidic & Alkaline Solvents (e.g., formic acid, acetic acid, ammonia, sodium hydroxide solutions).
-
Challenges:
Highly corrosive to metals. Can generate heat when mixed with water. Fume exposure risks.
-
Safe Pumping Method:
Use plastic or PTFE-lined pumps (e.g., peristaltic or magnetic drive). Ensure adequate PPE (gloves, goggles, respirators). Use ventilation systems to remove fumes. Halogenated Solvents (e.g., carbon tetrachloride, chloroform).
-
Challenges:
Toxic and can cause environmental damage. Heavier than air, increasing containment issues.
-
Safe Pumping Method:
Use chemical-resistant Yamada diaphragm pumps. Employ closed-loop systems to prevent vapor escape. Ensure proper disposal handling.

Yamada diaphragm pumps feature a Patented Non-Lubricated Air Valve with a Non-centering Stall-free Spring, offering several key advantages:
1. Non-Lubricated Design
- Reduces Maintenance: Eliminates the need for continuous lubrication, lowering maintenance time and costs.
- Prevents Contamination: No risk of oil contamination in air exhaust or the fluid being pumped, making it ideal for sensitive applications like food, pharmaceuticals, and chemicals.
- Enhanced Reliability: Ensures consistent performance without requiring frequent service for lubrication.
2. Stall-Free Operation
- Non-Centering Spring Mechanism: Prevents the pump from stalling by keeping the air valve in motion, even in low-pressure or fluctuating conditions.
- Continuous Flow: Unlike traditional diaphragm pumps that may stall if pressures are unbalanced, the Yamada system ensures smooth and uninterrupted operation.
- Better Performance in Low Air Pressure Applications: Operates efficiently even in environments where air pressure is inconsistent.
3. Improved Efficiency
- Reduced Air Consumption: The efficient air valve system optimizes air usage, lowering operational costs.
- Lower Energy Costs: The pump runs more effectively with less compressed air demand, making it more energy-efficient.
4. Durability & Longevity
- Less Wear & Tear: Without the need for lubrication, there are fewer chances of gum buildup or air valve sticking, resulting in a longer lifespan.
- Reliable in Harsh Conditions: Works well in extreme environments, including those with moisture-laden air or dirty operating conditions.
5. Ease of Maintenance
- Simplified Air Valve Design: Makes servicing and repairing the pump faster and more straightforward.
- No External Lubricators Required: Reduces the number of components that need maintenance or replacement.
This patented system makes Yamada diaphragm pumps highly reliable and cost-effective, particularly in industries where downtime and maintenance costs are critical concerns.
