An experimental investigation is carried out on the characteristics of a gear pump to clarify the effects of side clearance and fluid viscosity. The gear of pump on test is of corrected involute type, 7 teeth, pressure angle 14° 30', module 4,pitch circle dia. 28 mm, external dia. 37.9 mm, teeth thickness 21.88 mm, theoretical displacement 17.14 cc/rev, tip clearance 0.05 mm, and side clearances are varied from 0.2 to 0.5 mm. Viscosities of the fluids are varied in the range 150〜5000 Redwood-seconds. It is shown that the effects of side clearance δ and viscosity ν can be expressed quite briefly using non-dimentional parameter Φ=H/n f(ν, δ), where H and n denote the manometric head and number of revolutions of the pump respectively, and f (ν, δ) is a function of ν and δ, which are characteristic to pumps.
