Since its inception in 1975 in Italy, OBL has established a global reputation for innovation in quality and durability. OBL pumps are designed to perform reliably in demanding chemical environments, meeting the varied needs of multiple industries. With a wide range of dosing pumps—including mechanical diaphragm pumps, plunger pumps, hydraulic pumps, and hydraulic diaphragm pumps—OBL offers precise dosing solutions suitable for applications from low to high flow rates. OBL products are widely used across industries, from car wash systems to offshore platforms.
Key Advantages of OBL Dosing Pumps
- Durability and Resilience in Harsh Environments: OBL pumps are crafted from high-quality materials such as stainless steel, Hastelloy, and corrosion-resistant plastics like PP, PVC, PVDF, and PTFE. This ensures consistent, long-lasting performance even in hazardous chemical conditions.
- Exclusive Mechanical Diaphragm Design: This design guarantees linearity between flow rate and stroke percentage, facilitating precise control and dosing, especially in applications requiring high accuracy.
- Versatile Dosing Solutions: OBL provides pumps with various wetted part materials, either metal or plastic, and a range of flow rates from small dosages up to 3.5 m³/h, making them adaptable for a wide array of industrial dosing requirements.
- Compliance with API 675 Standards: OBL’s plunger and hydraulic diaphragm dosing pumps conform to API 675 standards, making them ideal for high-pressure applications. The plunger pumps utilize ceramic pistons and simplified linear knobs, ensuring ease of operation and durability in challenging conditions.
- Safety and Self-Priming Capability: Integrated safety valves, air bleed valves, and mechanically activated auxiliary diaphragms not only enhance operational efficiency but also provide system safety. The self-priming capability allows for rapid startup and stable operation without manual intervention.
