Product Overview

The square manual oil pump is a hand-operated pump designed for transferring oils and other liquids. Its defining feature is a square pump body typically die-cast from aluminum alloy, offering robust construction and ease of installation and securing. This equipment operates without electrical power, relying solely on manual effort to perform suction and transfer of liquids.

Structure and Materials

The pump features a square design, with the body and base often integrally cast, providing good overall rigidity and stable mounting. Key components such as the pump body and handle are made from metal materials (e.g., aluminum alloy). Internal critical sealing elements utilize oil-resistant rubber or engineering plastics to ensure compatibility with the conveyed medium and service life.

Working Principle and Performance

The pump operates based on a piston or gear principle. Reciprocating the handle creates a pressure differential within the pump chamber, thereby achieving fluid intake and discharge. Its performance characteristics include:

• Self-priming Capability: Possesses a certain self-priming height, enabling liquid extraction from overhead containers or tanks.
• Controllable Flow Rate: The output flow rate is directly related to the operator's cranking speed, allowing for easy control.
• Media Compatibility: Suitable for transferring common oil products such as diesel, engine oil, and lubricating oil, as well as other non-corrosive, non-flammable, and non-explosive liquids.

Application Scenarios

Primarily used in locations without power supply or where open flames and electricity are prohibited, for example:

• Refueling or adding lubricant to agricultural machinery, construction equipment, and vehicles in field operations.
• Transferring fuel from drums or small storage tanks.
• Routine withdrawal and distribution of small quantities of oil in factories or warehouses.
• Serving as emergency backup equipment during power outages or similar situations.

Usage Notes

Before use, confirm the compatibility of the liquid being transferred with the pump materials. Operation should be steady, avoiding dry running and overload. Regularly inspect the condition of seals and keep the pump body clean to ensure proper operational performance.
