LEITENBERGER Mess- und Regeltechnik GmbH presents this excellent quality manual transfer pump, manufactured in Germany, which offers an ideal solution for the safe and efficient transfer of liquids such as oils, brake fluids, and other non-flammable, non-aggressive media. This robust device, made of aluminum, is designed for professional use, ensuring reliable operation in cooling technology, industrial measurement, and testing applications.
This manual transfer pump (part number: HAP 21_C) combines ease of handling with a durable design. The aluminum construction guarantees a long service life and low weight, while the height-adjustable design provides flexibility for adapting to different container sizes.
Main Advantages:
Material quality: Housing made entirely of aluminum, which provides excellent resistance to non-aggressive media.
Adjustable Height: The length of the pump can be easily adjusted in the range between 400 mm and 700 mm, thus optimally fitting various sizes of barrels and containers.
High Pressure Capability: Capable of reaching up to 30 bar pressure, which is sufficient for most standard transfer tasks.
Versatile Connections: Different connection options enable broad compatibility with existing systems.

During the design of the HAP 21_C pump, user-friendly operation and reliability were the main focus. The telescopic design of the pump allows the user to precisely align the suction tube to the bottom of the barrel, thus minimizing residual fluid.
Adjustability and Flexibility:
The length adjustment range extending from 400 mm to 700 mm is extremely useful, as standard barrels and containers available on the market can have different heights. The operation of the pump is simple, manual force is used, and with a stroke length of approx. 270 mm, the fluid can be moved effectively.
Connection System:
The pump features three key connections:
Pump Connection (Outlet): The 1/4″ SAE standard connection provides the pressurized outlet to which the appropriate hose (HAP21C_Schl-SAE) can be connected for the targeted discharge of the fluid.
Barrel Connection (Suction Side): The 41/24 size rubber cup guarantees a tight, leak-free fastening at the barrel opening, which is critical for maintaining vacuum.
Suction Connection (Inner Pipe): The 1/4″ BSP connection serves for connecting the suction-side PVC hose (HAP21C_Schl-PVC), which transports the fluid from the container to the pump body.
Application Areas:
Although the pump is primarily ideal for pumping oils and brake fluids, it can be excellently used in any industrial environment where non-corrosive, non-flammable fluids must be reliably handled, such as:
Vehicle services (brake fluid, engine oil changes)
Cooling and air conditioning systems (handling certain types of oils)
General maintenance tasks in laboratories and workshops.
The maximum pressure capability of 30 bar ensures that the pump operates effectively even with more viscous fluids and can place the fluid at the required height or under pressure. The net weight of only 500 grams (without accessories) makes the tool extremely portable.
This LEITENBERGER product guarantees German engineering precision, providing long-term, trouble-free performance even in the most demanding professional environments.
