Products Description
OS-30BG Triplex Plunger Pump | Belt-Driven High-Pressure Pump Assembly for Agricultural Power Sprayers, Pressure Washers & Industrial Fluid Transfer
Brass Manifold Triple-Piston Pump with Adjustable Pressure Regulator, Integrated Pressure Gauge, Dual Outlet Manifold & 3-Spoke Cast Iron Drive Pulley
OS-30BG Plunger pump
The OS-30BG is a triplex (three-piston) plunger pump built for belt-driven operation from a gasoline or diesel engine - the power configuration used in tractor-mounted sprayers, trailer spray rigs, engine-driven pressure washers, and stationary high-pressure cleaning stations. Its brass manifold head with stainless steel valve assemblies resists the corrosion and pitting that agricultural chemicals and hard water cause in aluminum-manifold economy pumps. The three-piston design smooths pressure pulsation compared to single or duplex pumps, delivering steady discharge pressure with minimal surge - critical for uniform spray nozzle output across a multi-nozzle boom.This is a complete kit, not just a bare pump. It includes the belt-drive pulley, adjustable pressure regulator with integrated gauge, dual outlet manifold with individual shut-off valves, high-pressure delivery hose, suction hose with strainer, mounting brackets, tools, and a full seal/O-ring replacement kit - everything required for installation and first-season maintenance in one package.
Technical Profiles & Materials
Brass Manifold with Stainless Steel Valves - Corrosion Resistance That Lasts：
The pump head is precision-machined from forged brass, with stainless steel check valve seats, springs, and poppets. Brass resists dezincification - the selective corrosion that turns standard brass brittle and porous after prolonged exposure to acidic spray chemicals and hard water. The stainless internals prevent the rust-particle contamination that clogs spray nozzles. Combined, the brass-stainless metallurgy extends service intervals compared to aluminum-head pumps by a factor of two to three in aggressive chemical service.
Triplex Plunger Design - Smooth Flow, Low Pulsation：
Three ceramic or hardened-stainless plungers reciprocate 120 degrees out of phase, each driven by the crankshaft through connecting rods and crosshead guides. This phase offset means at least two plungers are always delivering flow, producing a discharge pressure ripple that is a fraction of a single or duplex pump. For sprayer booms with 10–20 nozzles, uniform pressure means uniform droplet size and even coverage - no strips of over- or under-application from pressure surge..

Products Application
Vehicle-Mounted Spray Rigs & Municipal Equipment
Small truck and ATV-mounted spray rigs for roadside weed control, mosquito fogging pre-treatment, and turf management use belt-driven plunger pumps for their combination of high pressure, chemical tolerance, and mechanical simplicity. The OS-30BG's adjustable regulator allows the operator to dial pressure down for sensitive turf applications or up for deep-soil injection. The included seal and O-ring kit gives fleet maintenance workshops the spares to perform a full pump reseal in the field - minimizing the downtime cost of a grounded spray vehicle during peak application season.
High-Pressure Washers & Industrial Cleaning
The same pump platform, when driven by a 7–13 HP gasoline or electric motor, becomes the pressure-generating core of a stationary or mobile high-pressure washer. The triplex design delivers the smooth, surge-free pressure that flat-surface cleaners, rotary nozzles, and foam cannons require for even cleaning - pressure ripple causes streaking on concrete, uneven chemical application, and operator fatigue from pulsating trigger feedback. For equipment fabricators building custom pressure washer skids, the complete-kit format simplifies procurement and assembly.
Agricultural Boom & Orchard Sprayers
The OS-30BG is designed for tractor-mounted and trailer-type sprayers applying pesticides, herbicides, fungicides, and liquid fertilizers across field crops, orchards, vineyards, and plantations. Belt-driven from the tractor PTO or a dedicated engine, the pump delivers steady pressure to multi-nozzle spray booms 6–18 meters wide. The brass manifold and stainless valves tolerate the full spectrum of agricultural chemicals - glyphosate, paraquat, copper fungicides, and acidic foliar feeds - without the corrosion that disables aluminum-head pumps within two seasons.

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.
