Hand Pressure Oil Pump
The HP-5 hand-operated oil lubrication pump is a compact manual oil supply unit designed for periodic lubrication of machine tools and industrial equipment. It combines a lever-operated pumping mechanism, a transparent 0.5 L oil reservoir, an outlet connection, and an integrated mounting bracket.
The manual operating design does not require an electrical power supply, making the HP-5 suitable for machine tools, machining centers, injection molding equipment, printing machinery, and selected centralized lubrication systems. The transparent reservoir allows operators to observe the oil level during routine equipment checks.
Product Introduction
The HP-5 is a hand-operated oil lubrication pump used to deliver clean lubrication oil to machine components that require periodic manual oil supply. It is suitable for applications where an automatic electric lubrication pump is unnecessary or where a simple manually controlled lubrication method is preferred.
When the operating lever is pressed, the internal pumping mechanism draws oil from the reservoir and delivers it through the outlet connection to the connected lubrication line. The provided product specification lists a reservoir capacity of 0.5 L and a rated flow of 5 ml/min.
The transparent oil reservoir helps operators monitor the remaining oil level without opening the pump. Its mounting plate allows the unit to be installed on a machine frame, equipment enclosure, or other suitable supporting surface.
This manual oil lubrication pump can be used as part of a centralized oil supply arrangement for guideways, sliding mechanisms, feed systems, and other machine components. Final suitability depends on the required pressure, outlet connection, lubrication point arrangement, oil viscosity, and installation dimensions.

Product Features
Manual Operation Without Electrical Power
The HP-5 uses a lever-operated pumping mechanism and does not require a motor, driver, controller, or electrical connection. This makes installation simpler in applications requiring periodic manual lubrication.
0.5 L Transparent Oil Reservoir
The transparent reservoir allows operators to check the approximate oil level during routine inspections. This helps maintenance personnel identify when the reservoir needs to be refilled.
Controlled Manual Oil Delivery
The provided specification lists a rated flow of 5 ml/min. Manual lever operation gives the operator direct control over when lubrication oil is supplied to the connected system.
Compact Installation Dimensions
The pump has a compact body with an approximate overall width of 115 mm and an overall height of 125 mm. It can be considered for machines where the available installation area is limited, subject to mounting verification.
Integrated Mounting Bracket
The metal mounting plate includes installation holes for securing the pump to an appropriate machine surface. Buyers should confirm the mounting span, hole positions, and installation direction before ordering.
Suitable for Clean Lubrication Oil
The operating information supplied with the product specifies the use of clean lubrication oil. Clean oil helps reduce the risk of contaminants entering the pump, outlet line, and connected lubrication points.
Practical for Equipment Maintenance and Retrofit Projects
The HP-5 can be considered for new equipment, maintenance replacement, and retrofit projects. Compatibility must be checked against the original pump model, installation dimensions, outlet specification, required pressure, and lubrication medium.
Product Application
The HP-5 is designed for equipment requiring controlled manual oil supply rather than continuous automatic lubrication.

Packing, Storage, Handling and Transportation
Packing
The HP-5 pump should be protected against impact, contamination, and compression during shipment. Packaging may include a protective bag, internal cushioning, a reinforced carton, product identification, and quantity verification.
The final packaging method is selected according to the order quantity, destination, and transportation method.
Storage
Store the pump in a dry, clean, and ventilated environment. Keep it away from corrosive gases, excessive humidity, direct water exposure, and heavy dust.
Keep the original packaging in place before installation whenever possible. Avoid placing heavy products directly on the operating lever or transparent reservoir.
Handling
Handle the pump carefully and avoid dropping, collision, or pressure on the reservoir. Do not lift or carry the pump by the outlet fitting alone.
Protect the mounting plate, outlet connection, filling components, and operating lever from deformation during warehouse handling.
Transportation
The product can be packed for international express, air freight, sea freight, or rail transportation according to the order requirements.
Before shipment, the model, quantity, visible condition, and packaging condition should be checked. Consolidated shipment with other LONGQIAO CNC components can be discussed according to the purchase plan.
