• Black anodizing Aluminium casing;
• Simple and robust spring return plunger pump;
• Low cost, due to reduced number of components;
• Ideal for metering of mild or non-aggressive fluids;
• ATEX STD compliance (94/9/CE), group II category
2 (zone 1/21) and group II category 3 (zone 2/22);
• Single and multiple arrangement.

Applications: Theses pumps are used in Oil Refinery, Food and Pharmaceutical industries.

High pressures are no problem in metering systems as long as there is something to counter them. OBL hydraulic diaphragm metering pumps therefore use a hydraulic fluid to create back pressure. You will soon notice the benefits for the diaphragm.

Technically advanced hydraulic diaphragm metering pump;

• Combines the simplicity and economics of the spring return with the advantages of the hydraulic diaphragm using an innovative mechanically actuated oil replenishing system;
• Built-in relief valve on the oil circuit to protect the pump against over pressure;
• Can be used in both process and service applications;
• Minimum maintenance required;
• ATEX STD compliance (94/9/CE), group II category 2 (zone 1/21)

and group II category 3 (zone 2/22).
