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).

Mechanism: Spring return

Max flow rate: 300 L/h

Flow :2 to 300 L/Hr

Pressure : -5 to 100 Bar

• 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.
