Yamada Pumps for Antifreeze, Coolant, Ethylene Glycol or Propylene Glycol
Yamada® Air-Powered Double Diaphragm Pumps are designed to handle antifreeze coolant applications. Ethylene glycol has thermal properties which include a high boiling point, low freezing point, stability over a wide range of temperatures, and high specific heat and thermal conductivity. It also has a low viscosity and, therefore, reduced pumping requirements.
The ethylene glycol in the antifreeze can cause the rubber to become brittle and crack, leading to premature failure. It can also cause the rubber to swell and become soft, resulting in loss of strength and elasticity. In some cases, it can cause corrosion of the rubber material, leading to further weakening. We recommend that if you are experiencing failure it is because antifreeze pump wetted elastomer materials should be made of PTFE, Neoprene, Buna N, Hytrel or Santoprene.
Yamada Petroleum pumps provide a range of benefits including intrinsically safe operation, resistance to burning out on dry run or deadhead applications, and suitability for shear-sensitive fluids. They offer a small footprint and portability, with the ability to run on natural gas or compressed air. Additionally, these Antifreeze pumps have solids handling capabilities, are CSA certified, and have UL listed models available. They are suitable for a variety of applications such as sumps, filtration, drum unloading, potable water transfer, and more.

Our Pumps
Challenges of Pumping Antifreeze: Yamada Pumps make it safe and efficient.
-
Use a Compatible Pump
Choose a pump made of chemical-resistant materials (stainless steel, polypropylene, or PTFE seals). Diaphragm pumps, peristaltic pumps, or gear pumps are often best for antifreeze applications.
-
Select the Right Flow Rate and Pressure
Ensure the pump has enough power to handle antifreeze viscosity, especially in cold conditions. Use a self-priming pump for efficient operation.
-
Maintain a Clean System
Flush the system before and after use to prevent contamination. Use dedicated hoses and storage containers for antifreeze only.
-
Use Proper Containment and Spill Prevention
Work in a controlled area with secondary containment trays. Have spill kits and absorbent materials on hand.
-
Temperature Control Measures
If working in cold environments, store antifreeze in a temperature-controlled area before pumping. Use a heated pump or insulated hoses for extreme cold conditions.
-
Wear Protective Gear
Use gloves, safety goggles, and protective clothing to prevent skin or eye exposure. Ensure proper ventilation if working in confined spaces.
-
Follow Proper Disposal Procedures
Never dump antifreeze down the drain or on the ground. Collect and dispose of used antifreeze through approved recycling or disposal facilities.
Using a Yamada diaphragm pump to pump antifreeze offers several advantages, including:
-
Chemical Compatibility
Yamada diaphragm pumps are built to handle a variety of chemicals, including antifreeze (ethylene glycol or propylene glycol). They can be made from materials like Santoprene, Viton, or Teflon, which resist chemical corrosion.
-
Self-Priming
These pumps can run dry and self-prime from significant suction heights, making them ideal for transferring antifreeze from drums, containers, or reservoirs.
-
No Seal Leaks
Since Yamada diaphragm pumps use a flexible Yamada diaphragm rather than rotating seals, they eliminate issues with seal wear and leaks, which are common in other pump types handling antifreeze.
-
Handles Viscosity Variations
Antifreeze can vary in viscosity depending on temperature. Yamada diaphragm pumps can handle thicker fluids better than centrifugal pumps.
-
Variable Flow & Pressure Control
Most Yamada diaphragm pumps allow easy flow rate adjustments without complex control mechanisms, making them ideal for metering antifreeze in different applications.
-
Explosion-Proof / Pneumatic Operation
Many Yamada diaphragm pumps operate on compressed air, making them safe for use in hazardous environments where electrical pumps might pose a risk.
-
Durability & Longevity
With fewer moving parts and no metal-to-metal contact inside the fluid chamber, Yamada diaphragm pumps experience less wear and tear, leading to longer service life.
-
Portable & Versatile
Many models are lightweight and portable, allowing for easy transfer of antifreeze in automotive, industrial, and HVAC applications.
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.
