22 & 26 Plunger Pump Pressure Gauge | 100 bar / 10 MPa Dual-Scale Dial Gauge for Agricultural Backpack & Trolley Power Sprayers
Color-Coded Green/Yellow/Red Operating Zones with Threaded Bottom-Mount Connection
22 plunger pump 26 plunger pump pressure gauge
This pressure gauge is a direct-mount dial instrument designed for 22 mm and 26 mm triplex plunger pumps - the core pressure-generating component in backpack and trolley-type agricultural power sprayers. It monitors pump discharge pressure in real time, giving the operator immediate visual feedback on whether the spray system is operating within its safe working range, developing a blockage, or experiencing a pressure drop from a clogged nozzle or leaking hose.
The gauge reads up to 100 bar (10 MPa) across two concentric scales, with a color-coded dial face that eliminates the need to read numbers during operation: green zone (0–40 bar) for normal spraying, yellow zone (40–60 bar) for caution, and red zone (60–100 bar) for over-pressure warning. This is critical safety information on a sprayer - a blocked nozzle or kinked hose can spike pressure to pump-damaging levels within seconds.
Technical Profiles & Materials
Dual-Scale bar / MPa Display - International Readability：
The outer scale reads in MPa (0–10, black markings) and the inner scale reads in bar (0–100, red markings). Bar is the standard pressure unit for agricultural sprayer pumps globally; MPa is the industrial/metric equivalent. Having both on one dial serves operators accustomed to either system without conversion. The color-coded green/yellow/red arcs are applied behind the scale markings, making zone identification instant - the operator sees a red needle entering a red zone, not a number.
22 mm & 26 mm Plunger Pump Compatibility：
The gauge's threaded bottom stem is machined to the standard pressure-sensing port thread found on 22-type and 26-type triplex plunger pumps. These two pump sizes dominate the knapsack and trolley sprayer market: 22 mm plungers (typically delivering 15–25 L/min at 15–35 bar) for standard backpack units, and 26 mm plungers (20–40 L/min at 20–45 bar) for higher-output trolley and vehicle-mounted sprayers. One gauge SKU fits both pump families, reducing inventory complexity for dealers stocking spare parts.

Products Application
Agricultural Backpack Power Sprayers
The dominant fitment. Millions of backpack sprayers powered by 2-stroke or 4-stroke engines are in daily use across Asia, Africa, and Latin America for pesticide, herbicide, and foliar fertilizer application on rice paddies, vegetable farms, orchards, and plantations. The pressure gauge threads directly into the pump head's gauge port and displays real-time discharge pressure to the spray wand. A working gauge prevents the most common sprayer failure mode: a partially blocked nozzle that sends pressure spiking into the red zone, blowing the pump's plunger seals or splitting the delivery hose.
Trolley & Vehicle-Mounted Sprayers
Higher-capacity 26 mm plunger pumps are fitted to hand-pushed trolley sprayers and small-vehicle-mounted spray rigs used for larger plots, greenhouse rows, and roadside vegetation control. These pumps operate at higher flow rates and are more sensitive to downstream blockage - a kinked delivery hose on a 26 mm pump can exceed 60 bar in under three seconds. The gauge provides the operator with a pressure reading at the pump head, independent of whatever nozzle arrangement is at the end of a 50-meter hose run.
Pump Pressure Testing & Diagnostic Tool
Beyond continuous installation, the gauge serves as a diagnostic tool for pump condition assessment. Removing the spray wand and dead-heading the pump against the gauge reveals maximum pump pressure - a pump that can't reach its rated pressure has worn plunger seals, a failing check valve, or a damaged diaphragm. This 30-second test identifies the need for a seal kit before the pump fails in the field. For sprayer repair shops and agricultural equipment dealers, keeping one gauge on the diagnostic bench covers the two most common pump sizes they service.

FAQ
Q: Are you an impartial industrial components dealer or a direct China water pump factors factory?
A:We are a direct, ISO9001-certified engineering water pump components manufacturing facility and precision fluid-control factor manufacture exporter primarily based in China. We function our personal cleanroom injection molding bays, computerized ultrasonic welding arrays, computerized hydraulic stress check stations, and clean-room packaging lines, passing direct-factory wholesale price financial savings straight to your element procurement margins.
Q: Can your manufacturing unit furnish full certification forms for food-contact or consuming water compliance?
A: Yes, absolutely. For food, beverage, or scientific applications, our manufacturing unit makes use of one hundred percent virgin, un-recycled polypropylene resins accompanied by means of fabric traceability certificates. We mechanically furnish B2B purchasers with complete FDA compliance documentation, NSF-grade compound declarations, and RoHS/REACH chemical protection screening sheets to make certain clean clearance thru worldwide customs.
Q: Do you provide customization picks for distinctly corrosive fluids like sturdy acids or ozone?
A: Yes, we are a thoroughly succesful OEM/ODM supplier. For aggressive chemical or ozone environments, we can improve the 12x26.5mm valve configuration in our factory: substituting the general PP housing with top class PVDF (Fluoropolymer) and changing any steel springs with Hastelloy or whole springless gravity-ball architecture, making sure final chemical resistance.
Q: How do we impervious a pattern batch to execute computerized lifecycle and burst-pressure testing?
A: We relatively inspire complete laboratory contrast earlier than logging mass grant agreements. We can ship a pattern lot of 5-10 gadgets of our inventory 12x26.5mm take a look at valves for assessment (setup costs and DHL/FedEx air freight apply). Once the factors pass by your inner lifecycle verification and a formal wholesale quantity manufacturing contract or container run is locked in, the sampling charges are a hundred percent credited returned to your industrial balance.
