# Leitenberger Manual Transfer Pump (HAP 21_LR) \u2013 Precision Fluid Handling<\/p>\n
The Leitenberger Manual Transfer Pump (HAP 21_LR) is a robust and reliable device specifically designed for the precise pumping of various fluids, such as oils, and non-flammable and non-aggressive, corrosion-free media. As a result of outstanding quality German engineering, this pump offers an ideal solution for service and maintenance tasks, especially in cooling systems and lubricant handling.<\/p>\n
The HAP 21_LR model is made of aluminum, which guarantees a long service life and easy handling. The pump's design allows it to draw fluid directly from a canister or tank and deliver it to the desired location (e.g., an oil sump or a cooling compressor).<\/p>\n
## Main Features and Advantages<\/p>\n
This manual transfer pump features several functions that facilitate and make the work safer:<\/p>\n
* **Aluminum Construction:** The pump body is made of durable aluminum, which resists corrosion and ensures long-term reliability.
\n* **Can Fixing Union Nut:** The special threaded connection (union nut) allows for a tight and sealed fastening of the pump to the can. This feature ensures the pump remains on the container until it is completely empty, minimizing the risk of leakage and handling time.
\n* **Adjustable Height:** The length of the pump is adjustable (between 400 mm and 700 mm), allowing it to flexibly adapt to containers and cans of various sizes.
\n* **High Pressure Capacity:** The maximum achievable pressure is 30 bar, providing sufficient force to move more viscous oils or harder-to-pump media.
\n* **Efficient Suction Performance:** It can transfer approximately 400 ml of fluid per stroke, enabling fast and efficient work.
\n* **Universal Connection:** The pump features a 1\/4 SAE standard connection made of brass for outstanding durability.<\/p>\n
