HL-30H 30# Plunger Pump - High-Pressure Triplex Plunger Pump for Agricultural Sprayer & Power Spraying Systems
Heavy-Duty Blue Cast-Iron Plunger Pump with Brass Pump Head - PTO-Drive Compatible High-Pressure Liquid Delivery for Orchard
HL-30H 30# Plunger pump
The HL-30H 30# Plunger Pump is a professional-grade triplex plunger pump engineered for high-pressure liquid delivery in agricultural sprayer systems, orchard spraying equipment, plantation chemical application machinery, and industrial pressure washing applications. The pump features a robust blue cast-iron crankcase housing - providing the structural mass and rigidity required to absorb the cyclic pressure loads generated by high-pressure triplex plunger operation - paired with a polished brass pump head assembly housing the three plunger cylinders, inlet and outlet check valves, pressure regulator, and hydraulic connections. The 30# designation indicates the pump's rated operating pressure class, positioning it in the medium-to-high pressure range suited to professional boom sprayer, air-blast orchard sprayer, and mist sprayer applications where consistent pressure delivery across a multi-nozzle circuit is required for uniform spray coverage. The pump is driven via a direct shaft connection compatible with tractor PTO outputs, gasoline engine shaft drives, and electric motor drives - making it a versatile power source-agnostic pump unit for diverse sprayer platform configurations. An oil sight glass on the crankcase enables quick visual confirmation of lubricant level without disassembly, supporting the routine maintenance practices that protect plunger seal and crankshaft bearing service life.


Technical Profiles & Materials
1. Blue Cast-Iron Crankcase - High-Rigidity, Vibration-Damping Pump Housing The pump crankcase is cast from grey iron - the material standard for professional-grade plunger pump housings requiring the combination of high compressive strength, vibration damping, and dimensional stability under sustained cyclic pressure loading. The blue powder-coat or enamel finish protects the cast iron from the chemical splash and humidity exposure inherent in agricultural spraying environments. The heavy cast housing mass provides natural vibration damping that reduces the structural noise and vibration transmitted to the sprayer frame and tractor PTO connection under full-load operation - important for operator comfort and sprayer frame longevity on high-duty-cycle commercial spray systems.
2. Triplex Brass Pump Head with Check Valve Assembly The pump head is manufactured from brass - providing the corrosion resistance required for sustained contact with pesticide, herbicide, and liquid fertiliser solutions across all agricultural spray applications. The triplex (three-cylinder) plunger arrangement delivers significantly smoother, lower-pulsation flow compared to single or duplex pump configurations - critical for maintaining consistent nozzle pressure distribution across multi-nozzle boom and air-blast sprayer circuits. Each plunger cylinder is equipped with spring-loaded inlet and outlet check valves that maintain unidirectional flow and consistent pressure delivery throughout the pump stroke cycle.
3. Integrated Pressure Regulator & Oil Sight Glass - Field Serviceability The integrated pressure regulator valve - identifiable by the red adjustment handle visible on the pump body - allows the operator to set and maintain the target operating pressure from the pump outlet without requiring separate inline pressure control equipment. The oil sight glass on the crankcase side panel enables visual lubricant level checks during pre-start inspection without tools or disassembly - supporting the routine maintenance discipline that is the primary determinant of plunger pump service life in commercial agricultural spray operations.

Products Application

Sprayer & High-Pressure Boom Sprayer Systems
Commercial orchard operators and large-scale vegetable and fruit growers running tractor-mounted air-blast or boom sprayer systems require a high-pressure pump that delivers consistent outlet pressure across the full multi-nozzle circuit at rated flow volume - the core performance requirement that determines spray coverage uniformity across the entire spray boom width. The HL-30H's triplex plunger configuration and integrated pressure regulator maintain stable outlet pressure under varying nozzle load conditions, ensuring that all boom nozzles operate within their rated pressure range and produce the correct droplet size and pattern for uniform canopy coverage across large commercial field areas.

Plantation Chemical Application & Large-Scale Pest Management
Plantation operators managing large areas of rubber, oil palm, coffee, or fruit trees for systematic pesticide, fungicide, and foliar fertiliser programmes require high-pressure pump systems capable of sustained full-load operation across full working days in high-ambient-temperature tropical environments. The HL-30H's cast-iron crankcase and brass pump head construction provide the thermal mass and material durability required for extended duty-cycle operation, while the integrated oil sight glass and pressure regulator support the field maintenance practices that prevent premature pump failure during intensive plantation spray programmes.

Contract Spraying Services & Agricultural Machinery RentaL
Agricultural contractors providing crop protection spraying services across multiple client farms - and agricultural machinery rental businesses supplying sprayer equipment - require high-pressure pumps that deliver reliable performance across diverse operating conditions, chemical types, and operator skill levels. The HL-30H's robust cast-iron and brass construction, integrated pressure control, and PTO-compatible drive interface make it a practical pump selection for contract and rental sprayer builds where pump reliability directly determines service quality, equipment utilisation rate, and the contractor's ability to fulfil spraying schedules across multiple client sites during time-critical crop protection windows.

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.
