Axial-piston pump

Mon, 20 May 2013 19:31:00 +0000

The V60N-130 joins the V60N Series of axial-piston pumps. The Series now consists of four different sizes with displacement volumes up to 8 in.3/rev, working pressures of up to 5,800 psi, and peak pressures of up to 6,500 psi. All pumps have swash plates and provide required displacement volume without over or underdimensioning the pump output.

Diaphragm pumps

The 1010 Series gas diaphragm pump offers 4,000 hr of nonstop operation. The efficient operation and low power consumption of the 0.03-lb unit extends the battery life of the warning device. Features include oilless operation, a sealed air path for contamination-free analysis, and a restart option at low temperatures for use in cold environments.

Customizable cylinders are small but powerful

NFPA tie-rod hydraulic cylinders are powerful devices, but they’re generally pretty hefty. The smallest standard size usually has a 1.5-in. bore, according to officials at Nason, Walhalla, S. C. (www.nasonptc.com). The company’s L15 hydraulic cylinders, on the other hand, are rated for 1,500 psi of pressure but come in bores down to 20 mm, giving engineers a viable option when jobs need lots of force in tight spaces.
