13 POWERFUL SOLUTIONS. GLOBAL FORCE. Tough Dependable Innovative ATEX 95 Certified The Enerpac ZA4-series air pumps are tested and certified according to the Equipment Directive 94 / 9 / EC “ATEX Directive” for equipment and protective systems intended for use in potentially explosive atmospheres. • ATEX 95 certified for use in potentially explosive atmospheres • Features Z-Class high efficiency pump design, higher oil flow and bypass pressure • Two-speed operation reduces cycle time for improved productivity • User adjustable relief valve built-in on manual valves. Oil ports on valves are 3/8" NPTF • Optional heat exchanger warms exhaust air to prevent freezing and cools the oil • Full sight oil level glass on 10, 20 and 40 litres reservoirs, oil level indicators on 4 and 6,6 litres reservoirs. Speed Chart To determine how a specific pump will operate your cylinder, see the Pump-Cylinder Speed Chart in the ‘Yellow Pages’. Hoses Enerpac offers a complete line of high quality hydraulic hoses. To ensure the integrity of your system, specify only genuine Enerpac hydraulic hoses. Used with Cylinder 1 See pages 116-117 for hydraulic symbols of these valves . 2) Actual oil flow will vary with air supply . 3) Dynamic air pressure range: 4 - 7 bar .
