You buy one when a shop cannot stop. If a single compressor goes down for a valve plate or a belt, the whole floor goes quiet; on a duplex, the second pump carries the load while the first is serviced. The same arrangement also lets both pumps run together through a morning rush and then run lead\/lag the rest of the day, which keeps each pump's duty cycle and head temperature well inside its comfortable range.\u003c\/p\u003e\n\u003cp\u003eThese are the factory Advantage duplex packages from the Champion Reciprocating price book: fixed configurations, fully equipped, freight prepaid.

The HR5D-12 duplex delivers 34.6 ACFM against the VR10-12 simplex at 33.8, so the air is comparable. The duplex gives you redundancy and a gentler duty cycle; the simplex is lighter, cheaper and takes less floor. Buy the duplex if downtime costs you money.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I run both pumps at once?\u003c\/strong\u003e Yes. The duplex control alternates the lead pump and brings the second in on demand, so both run together under heavy load and share the hours evenly over time.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy does the 7.5 HP duplex use a different pump from the 7.5 HP simplex?\u003c\/strong\u003e Champion specifies the larger R30 pump at 570 RPM on the duplex rather than two R15 pumps at 949 RPM. Slower pump speed on a larger pump means lower piston speed, cooler running and longer life on a machine expected to run long hours.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo these come with a control panel and starter?\u003c\/strong\u003e Yes. A mounted NEMA 1 Level 2 panel with hour meter and Test-Off-Auto switch is standard, as are low oil stop control and the electric timed tank drain. Nothing on the standard features list is an extra cost option.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat about 460 volt?\u003c\/strong\u003e The Advantage duplex packages are built in 208 and 230 volt only.
