Leak-free external-gear pumps that provide precise, non-pulsing flows from 1 ml/min to 10 USGPM (38 lpm), differential pressures to 250 psi (17.2 bar), system pressures to 500 psi (34.5 bar), temperatures to 350°F (176°C), viscosities to 2000+ cps.
GlobalGear? internal gear pumps have tougher, more reliable parts that are easy to service and maintain. The modular design reduces switching costs saving time and money. Magnetically coupled internal gear pumps designed to provide zero leakage. Circumferential piston pumps for the most demanding applications. Capable of running dry indefinitely this pump is a severe-duty problem solver.
Tuthill lubrication and circulation pumps handle many viscosities and sustain a constant flow at any pressure. With only two moving parts the internal gear design allows the pump to handle higher viscosity liquids. Simple, Compact Design offers high efficiency and longer life. Positive Reversing Action - The unique reversing feature allows the lubrication and circulation pumps the ability to reverse flow without the use of valves.
