Top Advantages Of Using A Diaphragm Agricultural Pump

Business Technology

A diaphragm pump has very significant properties, which makes it suitable for use in agriculture. The main advantages of these pumps compared to centrifugal pumps are good dry running capacity, excellent head and self-priming capacity, resistance to corrosion and abrasion.

Diaphragm agricultural pumps are pumps that use alternating variations in chamber volume to generate pressure imbalance between the chamber and the adjacent spaces. The fluid naturally moves from the space with higher pressure to space with lower pressure. This results in a downward motion where the fluid ends up pumping itself.

Excellent self-priming capacity

Diaphragm agricultural pumps can create a good vacuum on the suction line. The diaphragm generates enough airtight seal and a vacuum on the suction line. This means that the pump can lift water from levels lower than where it is installed.

Diaphragm pump manufacturers make these pumps in a way they can be operated without filling the suction pipe. This is made possible by the fact that the pump can suck up the air in the suction pipe at the start-up phase and get rid of such air through the delivery line.

Good dry running capacity

There is an airtight separation between the oil-bath lubricated components of transmission and the pumping chambers and this makes it possible for the pumps to be able to withstand reasonable dry running periods without any negative consequences such as seizing up of the connecting rods and overheating. This can occur on centrifugal pumps as they cannot work dry.

Resistance to corrosion and abrasion

A diaphragm pump does not have any mechanical parts in direct contact with the liquid. This means that the pump can pump fluids that aren’t perfectly filtered with solid particles residues such as sand, crystals or crushed stone and can be used with most plant protection substances that are mostly water-based.
