ProVane pump
The ProVane pump has self-adjusting vanes to eliminate efficiency-robbing slip, thereby allowing it to maintain near-original output and consistency, even after significant wear. Available in both ductile iron and stainless steel, its heavy-duty rotor and low shaft-stiffness ratio, combined with its hydrodynamic bearing design, result in extended bearing life, improved efficiency and energy consumption, better volumetric performance, and longer life. Five sizes, ranging from 3/4-in. to 2-in., are available, with operating speeds of 1,200, 1,800 and 3,600 rpm and capacities from 1 to 100 gal/min.

Micro C-Series pumps
The Micro C-Series pumps, like the larger C-Series pumps, can be drained, flushed and cleaned without disassembly. Three models designed for transferring small doses in continuous applications are available: the MC500 for flowrates of 0.1–2.2 gal/min (0.4–8.3 L/min) at 72.5 psi (5 bar) maximum pressure; the MC250 for 0.05–1.1 gal/min at 145 psi; and the MC125 for 0.03–0.6 gal/min at 217.5 psi. The pumps feature sealless construction, are self-priming, and can be run dry for short periods of time. They measure 9.5 in. long × 5 in. high × 4.5 in. wide, and weigh 17 lb.
