Description
The Comet MP30 is a professional-grade, semi-hydraulic diaphragm pump engineered for medium-pressure applications. Known for its “Italian-made” reliability, it is a staple in the lawn care, pest control, and agricultural industries. Unlike smaller 12V pumps, the MP30 is designed for high-endurance tasks, delivering significantly more volume and pressure for large-scale spraying.
Key Features & Performance
-
Corrosion-Resistant Build: Constructed with anodized aluminum parts in contact with liquid, making it highly resistant to fertilizers, herbicides, pesticides, and de-icing fluids.
-
Semi-Hydraulic Twin Diaphragm: Features two diaphragms that provide a smooth, consistent flow with minimal pulsation, reducing wear on your spray nozzles and hoses.
-
Large Capacity Oil Bath: The crankcase is oil-lubricated to ensure long-term durability during continuous operation.
-
Self-Priming: Capable of pulling fluid quickly from a tank, even when the pump is located above the liquid level.
