Displacements for medium-duty piston pumps
news product and services
Valves are field serviceable Miniature component specialists Lee Products have introduced a new range of Chek Valves for use in purge air, water injection and liquid fuel applications, specifically for industrial gas turbines. The valves can be quickly disassembled to enable servicing to be carried out in the filed, using a rebuild kit, the company says. The valves are available with or without a removable, washable Hi-Bar safety screen incorporating a one-piece component, which is machined from a solid piece of bar and features laser drilled holes. The screen is capable of handling differential pressures up to 7500 psid (518 bar) without collapse. The valves, which can operate at temperatures up to 230°C, feature a stainless steel poppet design that, in combination with a Vespel® seat, allows for both low leakage and high flow. They are available as a purge air and water injection option, measuring 144 mm in length x 32 mm in width, or as a liquid fuel option which measures just 86 mm in length x 35 mm diameter.
Sump pumps protect municipal water Aquamedic has developed BasementSaver HP-Series (High Pressure), a new line of water powered backup sump pumps which can extend safe emergency pumping operation to up to 150 psi with approved backflow prevention to protect municipal water supplies. The line, part of the company’s WP-Series backup sump pumps, distributed by American pump specialist Basementsaver, offer the same efficient operation as the WPSeries pumps, but also provide approved backflow protection
for city water at pressures up to 150 psi, the company claims. “WP-Series water powered backup sump pumps are generally preferred over battery backup sump pumps in most basement protection applications,” said Tim Harnois, owner of +Aquamedic. “This is primarily due to the fact that these water powered units are far more reliable, having no moving parts to break and having no battery or charger
to maintain. Additionally, WP water powered backup pumps can run continuously as long as city water is available, whereas battery powered systems can only pump until the battery discharges.” The Basementsaver HP backup sump pumps can remove up to 2 gallons of basement sump water for every gallon of city water used and the HP-Series pumps extend the range of safe operation up to 150 psi, compared to about 100 psi for WP models.
Displacements for medium-duty piston pumps Diversified industrial manufacturer Eaton Corp has expanded two of its variable displacement piston pump series with additional displacements. Now available for the Series 70160 medium-duty, manual controlled pump are a new 21.6 cm³/r (1.32 in³/r) pump that has been added to the series that also includes 20.3 cm³/r (1.24 in³/r) and 23.6 cm³/r (1.44 in³/r) pumps. A new 35.1 cm³/r (210 in³/r) pump has been added to Series 70360 that also includes 40.6cm³/r (2.48 in³/r) and 49.2

cm³/r (3.00 in³/r) pumps. With these product line expansions, the Series 70160 and Series 70360 pumps can suit a wider range of flow requirements on construction, forestry, harvester, industrial, paving,
and turf care equipment, Eaton says. Both pump models offer a maximum rated speed of 3,600 revolutions per minute and maximum pressure capability of 345 bar (5000 psi). Design features include a square input shaft to facilitate linkage retention, tapered trunnion bearings that reduce noise and vibration, and lightweight, compact housings. Eaton’s series 70160 is equipped with a Society of Automotive Engineers (SAE) “A” mounting flange and series 70360 has an SAE “B” mounting flange.
Viking Pump launches CMD non-metallic series Viking Pump has developed the Composite Mag Drive (CMD) series, a new range of sealless, non-metallic pumps designed for liquid containment applications, including corrosive chemicals, volatile organic chemicals, and flammable liquids. Due to the CMD pump’s engineered-fluoropolymer and ceramic-wetted material design and construction, the series of pumps can handle a broad pH range and offers advanced durability, broader compatibility, and corrosion resistance, Viking says.

incorporates a magnet system with a patent-pending spline design that allows the magnet to self-align while floating on the shaft with no added fasteners. “Because our CMD series is designed and manufactured with fewer parts, the pumps require less, more simplified maintenance,” said John Hall, product manager. The CMD series has selflubricating, heavy-duty bearings with patent-pending bearing geometry that allows 30-minute dry-run capabilities
and a universal flange that allows for installation for both ANSI and DIN flanged systems. The CMD series includes an array of models with capacities at 1450 RPM ranging from 0.34 to 16.5 GPM (1.3 to 62.5 LPM), and capacities at 1750 RPM ranging from 0.4 to 20.0 GPM (1.5 to 75.0 LPM), with a maximum differential pressure of 150 psi (10 bar) and a maximum recommended operating temperature of 150°F (65°C). Both the RTP20 and RTP30 series fill rotor voids, allowing for faster and quieter
operation on viscous liquids. In addition, with a longer sealing land at rotor tips, the series provides enhanced efficiency when working with lower viscosity products. The RTP20 offers a capacity to 264 GPM (1,000 L/M / 60 m3/hr), pressure to 145 psi (10 bar), viscosity to 250,000 SSU (55,000 cSt), and operates in temperatures to +230°F (+110°C). The RTP30 offers a capacity to 340 GPM (1,283 L/M / 77 m3/hr), pressure to 17 psi (12 bar), viscosity to 250,000 SSU (55,000 cSt), and operates in temperatures to +300°F (+150°C).
