These hose pumps can run at lower speeds, increasing hose life

The Bredel APEX range of seal-less, valve-less hose pumps (photo) are designed for dosing, metering and transfer duties at flowrates ranging from 0.012 to 27.3 gal/min, at pressures up to 116 psi, and are suitable for chemically aggressive or abrasive processing. The higher flow-per-revolution value means that APEX pumps can be run at lower speeds, increasing hose life and reducing wear. Recent international product trials demonstrated that the newest APEX models can extend the time between scheduled maintenance intervals when compared with air-operated diaphragm pumps and progressive cavity pumps, according to the manufacturer.
