1:1 Air Operated Lubricating Oil Pump｜Equal Pressure｜Multi-Length｜Fits 20L/50L/200L Drums

The 1:1 ratio air-operated lubricating oil pump is an industrial-grade fluid delivery equipment powered by compressed air and designed with an equal-pressure plunger structure. Specially built for low-to-medium viscosity lubricants such as engine oil, gear oil and hydraulic oil, it provides three pump tube lengths to perfectly fit 20L, 50L, 200L standard drums and supports drop-in, drum-cap fixed and wall-mounted installation. It is widely used in production lines, centralized lubrication systems, auto repair, factory equipment maintenance, mining, port machinery and other scenarios, serving as the core power unit for stable and precise lubricant delivery.

This product delivers outstanding core values: 1:1 equal-pressure stable delivery with output pressure consistent with air supply, smooth pulse-free flow to avoid splashing and bubbling for precise filling; multi-length flexible adaptation with three options covering all drum sizes and installation styles; pure air-driven safety with no motor or circuit, stable in explosive-proof, oily, dusty and harsh environments; corrosion-resistant durable structure with chrome-plated stainless steel and brass valve core for long service life; super easy installation with drop-in or cap-mounted design, ready to work upon air connection with no complex debugging and extremely low maintenance cost.

Core Technical Parameters

Working pressure: 0.3~0.8 MPa (43~115 psi), complying with universal industrial air standards. Compression ratio: 1:1 equal-pressure delivery with smooth pulse-free flow; output pressure equals input pressure (max ≤0.8 MPa), safe without overpressure risk. Flow rate: 8~15 L/min, varies with air pressure and medium viscosity, high flow for batch filling and circulation. Applicable media: low-to-medium viscosity lubricants including engine oil, gear oil, hydraulic oil (not for high-viscosity grease). Air inlet: 1/4" NPT / G1/4 universal pneumatic thread; oil outlet: 3/8" NPT / G3/8 thread, directly connects to dispensing guns or lubrication lines. Pump tube lengths: short (20L), medium (50L), long (200L); installation: drop-in, drum-cap fixed, wall-mounted. Material: chrome-plated stainless steel + brass valve core, corrosion-resistant, wear-resistant and reliable sealing. Net weight: approx. 3~5 kg (varies by length), lightweight for single-person installation. Operating temperature: -10℃~60℃, cold and heat resistant for wide regional adaptation. Equipped with exhaust throttle valve for adjustable flow and pumping speed.

Core Functions & Advantages

Core Functions

1:1 Equal-Pressure Smooth Delivery: plunger-type equal-pressure structure keeps output consistent with air supply, pulse-free and stable, eliminating splashing and bubbling for clean and precise filling.Multi-Length & Multi-Scenario Adaptation: three tube lengths fully cover 20L, 50L, 200L drums, with drop-in, fixed and wall-mounted options for workshops, sites and repair shops.Pure Air-Driven Safety: no motor, no circuit, no spark, safe for high explosion-proof, oily and dusty harsh environments, free from electrical failures.Adjustable & Controllable Flow: built-in exhaust throttle valve freely regulates pumping speed and oil flow for precise control under different operation needs.Corrosion-Resistant Long-Life Structure: chrome-plated stainless steel body and brass valve core, oil-resistant, wear-resistant and stable sealing for long-term use.Fast Installation & No Debugging: drop-in or cap-mounted quick installation, ready to work once inserted into drum and connected to air supply, no complicated wiring or setup.

Product Comparative Advantages

Compared with common manual oil pumps, this 1:1 air-operated pump has comprehensive strengths: higher efficiency – manual pumping is slow and laborious while air-driven continuous output boosts efficiency by over 5 times; more stable flow – manual pump fluctuates and bubbles easily while 1:1 equal-pressure design ensures smooth and precise delivery; wider media compatibility – manual pump only for low-viscosity oil and prone to jamming while this pump fits full range of low-to-medium viscosity lubricants; stronger installation adaptability – manual pump limited to small drums while this pump fits 20L~200L drums with multiple installations; higher durability – manual pump with plastic/thin metal structure and easy damage while this pump features full metal anti-corrosion and wear-resistant construction for much longer service life.
