Pump Series


O Series®

O Series® pumps were originally designed for handling petroleum products.  Later, O Series pumps were introduced into the industrial market for effective handling of solvents and similar liquids, as well as excellent clean water handling.  The straight-in-suction design without a check valve eliminated entrance restrictions provides quick, reliable self-priming with few moving parts offering saving thru minimal maintenance and increased efficiency.  The O Series has a variety of seal configurations to choose from allowing it to handle a number of different liquids.

High-Efficiency Impeller
F_OSereis_1.jpg High efficiency, closed impeller. Brass or aluminum construction standard. Other metals available for special applications.
Long Life Seals
F_OSeries_2.jpg O Series pumps are available with self-lubricated mechanical shaft seals for dependability and long life. Viton®/Fluoroelastomers are standard. Teflon® and double seals available on some model. Consult factory for special applications.
Adaptability
O Series Pumps are available pedestal mounted for flexible coupling to a power source. Sturdy pedestal has heavy-duty shaft and ball bearings. Some models available close coupled to electric motors. Power take-off models incorporate pump gear increaser with helical gears for heads up to 400 feet (121 meters).
Straight-In Suction Design
F_OSeries_4.jpg O Series pumps have a straight-in suction design which eliminates entrance restrictions and provides better performance when handling petroleum products, solvents and similar liquids.
