Pompe de lubrification à manivelle

La pompe de lubrification à manivelle Y-8 est une unité d'alimentation en huile manuelle compacte, conçue pour les machines-outils et certains équipements industriels. Elle se compose d'un corps de pompe en aluminium moulé sous pression de 500 cm³, d'une poignée de manœuvre allongée, d'un voyant de niveau d'huile, d'un raccord de sortie en laiton et d'un filtre interne.

La pompe alimente en huile de lubrification grâce à l'actionnement manuel répété d'une poignée, sans nécessiter de moteur ni de raccordement électrique. Des configurations à sortie simple ou double sont disponibles, avec des options pour des tuyaux d'huile de 4 mm ou 6 mm. Le modèle Y-8 convient aux poinçonneuses, fraiseuses, équipements CNC, à la maintenance des machines et aux projets de remplacement nécessitant une méthode de lubrification à commande manuelle.

Présentation du produit

The Y-8 is a hand crank lubrication pump used to supply clean lubrication oil to machine guideways, sliding assemblies, feed mechanisms, and other designated lubrication points. It is intended for applications where periodic manual lubrication is preferred over an electrically powered lubrication unit.

The operator moves the extended handle repeatedly to actuate the internal pumping structure. Oil is drawn from the 500 cc reservoir and delivered through the brass outlet fitting into the connected oil pipe. Depending on the selected configuration, the pump can be connected to a 4 mm or 6 mm lubrication line and supplied with a single or double outlet.

A long transparent observation window allows maintenance personnel to check the approximate oil level without opening the pump body. The integrated filtering component helps reduce the entry of oil contaminants into the connected lubrication circuit. A check-valve structure in the outlet assembly helps limit oil return after operation.

The die-cast aluminum body provides a rigid enclosure for oily workshop environments, while four mounting holes allow the unit to be secured to a machine side panel or worktable wall. These structural features make the Y-8 suitable for machine manufacturers, maintenance companies, industrial distributors, retrofit specialists, and end-user factories.

Caractéristiques du produit

Cast aluminum alloy body

Integrated die-casting shell, rust and impact resistant, suitable for damp and oily environments in workshops, with higher strength compared to transparent plastic models, suitable for punching machines and heavy-duty milling machines.

Long handle hand-operated pressure structure

Extended metal joystick with anti slip rubber grip, generating oil supply pressure through reciprocating shaking, stable oil output, and effortless single person operation; There are two installation styles: left oil outlet and right oil outlet.

Long strip visible oil level window

The top long transparent observation window allows for a direct view of the internal lubricating oil inventory, avoiding dry grinding of machine tool rails due to oil shortage.

Brass oil outlet joint

Standard adaptation of 4mm lubricating oil pipe, built-in one-way check valve, no oil return in the oil circuit after shutdown, maintaining continuous oil storage in the guide rail.

Bottom flange installation hole

Reserved fixing holes on both sides, which can be directly locked on the side of the machine tool or the side wall of the worktable, and installed firmly without easy shaking.

Built in filtering components

The internal filter of the fuel tank is equipped with a filter screen to filter out impurities in the lubricating oil and protect the oil circuit and slider from blockage.

Application du produit

The Y-8 hand-cranked lubrication pump is designed for machines that require periodic and manually controlled oil supply. Its 500 cc capacity, rigid aluminum body, visible oil-level window, and flexible outlet configuration make it suitable for new machine installation, routine maintenance, and replacement projects. Final compatibility should be checked according to the machine’s lubrication requirements, pipe layout, required pressure, outlet quantity, and mounting dimensions.

Emballage, stockage, manutention et transport

Packing

The Y-8 is prepared with protective wrapping, internal cushioning, and reinforced outer packaging according to the order quantity and transportation method. The handle, filling cap, brass fitting, and mounting sections should be protected against impact and compression.

Product model, configuration, quantity, and visible condition are checked before final packing. Consolidated packaging can be arranged when the pump is shipped with other CNC machine components.

Storage

Store the pump in a clean, dry, and ventilated location. Keep it away from rain, corrosive gases, heavy dust, and excessive humidity.

The original packaging should remain in place before installation whenever possible. Avoid placing heavy products directly on the handle, oil-level window, filling cap, or outlet fitting.

Handling

Handle the pump carefully and avoid dropping or collision. Do not carry the unit only by the brass fitting or filling cap.

Protect the mounting holes, outlet connection, handle, and aluminum body from deformation during warehouse handling and order consolidation.

Transportation

Packaging can be prepared for international express, air freight, sea freight, or rail transportation. The final packing method depends on the quantity, destination, shipment method, and whether the order contains other products.
