Oscillating piston pumps

• compact
• automatic pressure limiter

The Gotec line of miniature pumps are suggested by the manufacturer for demanding print industry applications, including the direct handling of inks, solvents and related diluents. The units are self-priming to 5 or 10 feet, depending on the internal check valve configuration. The design automatically limits pressure, eliminating potential overloading. All of the pumps feature a design that has eliminated need for shaft seals. Configurable in material combinations including stainless steel, brass and acetal plastics, the Gotec line has models with flow rate capacities from 3-66 gph (10 to 250 liters per hour), and pressure ranges to 220 psi (25 bar). Other applications can include handling juices, lubricants, oils and water. Clark–Pump Solutions, Clinton, MA. Free info—Circle 440. www.RSLeads.com/110df-440
