ZA4-Series, Air <strong>Hydraulic</strong> Pumps<br />
� Shown: ZA4208MX, ZA4420MX<br />
• Features Z-Class high efficiency pump design, higher oil<br />
flow and bypass pressure<br />
• Two-speed operation reduces cycle time <strong>for</strong><br />
improved productivity<br />
• User adjustable relief valve built-in on manual valves.<br />
Oil ports on valves are 3/8” NPTF<br />
• Optional heat exchanger warms exhaust air to prevent<br />
freezing and cools the oil<br />
• Full sight oil level glass on 10, 20 and 40 litres reservoirs,<br />
oil level indicators on 4 and 8 litres reservoirs.<br />

1) See pages 135-139 <strong>for</strong> hydraulic symbols of these valves.<br />
2) For remote valve mounting order BSS1090 high pressure connecting plate.<br />
3) Actual oil flow will vary with air supply.<br />
4) Dynamic air pressure range: 4 - 7 bar.<br />
