What Is a Plunger Pump Used For?
A plunger pump is the pressure-generating core of agricultural spraying equipment. It is bought as a component by assemblers building sprayer units, and as a replacement by dealers supporting machines already in the field.
Unlike a centrifugal pump, it delivers steady pressure against resistance, which is what spraying requires — the nozzle is a restriction, and pressure has to hold behind it. That is why this pump type dominates agricultural spraying rather than water transfer.
For bulk buyers, this is a technical purchase. Customers arrive knowing what they need to match, and the conversation is about compatibility rather than persuasion.
What Do the Plunger Pump Specifications Mean?
Our Type 30 configuration runs three 30 mm plungers, delivering 33–40 litres per minute at a working pressure of 20–45 kg/cm². Those three numbers describe most of what an assembler needs to know.
Plunger count and diameter set the displacement; together with speed they set flow. Working pressure is the range the pump is built to hold — not a target to be exceeded, and running above it shortens seal life sharply.
Match the pump to the nozzles the machine will carry, not to the biggest number available. A pump delivering more flow than the nozzles can pass simply routes the surplus back through the relief valve, adding heat and wear without adding output.
How Does the Plunger Pump Fit the Rest of the Machine?
The pump is one of three decisions, alongside the power unit and the frame. Our built-up assemblies pair pumps with engines or motors on a range of frames — see the sprayer unit range for complete configurations.
Drive arrangement matters as much as the pump itself. Direct-drive and belt-driven layouts suit different speeds and different frames, and the pump has to be selected for the speed it will actually turn at.
For finished portable equipment rather than components, the knapsack power sprayer range covers the same application in a carried format.
What Should Distributors Stock?
Seals, plungers, valves and gaskets. A plunger pump is a serviceable component by design, and the distributor who can supply a seal kit keeps a machine in the field that would otherwise be replaced.
Confirm shaft, mounting and port specifications before ordering, since these decide whether the pump fits the customer’s existing frame at all.
