Zenith Pumps BMB/BMC Series

1 Zenith BMB/BMC Series Pumps offer the metering benefits of the wellknown Zenith BPB Series except in larger displacement control of critical process streams or additives is equallyimportant at higher flowrates, and Zenith BMB/BMC Series Pumps often pay for themselves in savings in less than one year when they are used to replace less accurate metering methods. The reliable, repeatable,pulseless metered flow from a Zenith pump improves process control and mixing while eliminating costly overdosing. Bene ts and Features High Accuracy - stable, repeatable ow control despiteprocess variations in temperature, viscosity, and pressure. High Pressure -precision manufacturing techniques holdtolerances to + .00005" ( micron), allowing gearclearances to be kept to a minimum and high processpressures to be achieved. Pulseless - precise, rotary spur gears provide smooth,continuous, pulseless ow. Valveless -precision metering gears eliminate trouble-some check valves used in reciprocating Pumps .

2 Active Flowmeter -unparalleled mechanical precisioncombined with a closed-loop Zenith ZeDrive 2000controller ensures exact ow control without the addition of expensive owmeters. Long Life -only three moving parts - componentsthrough hardened to Rc-54 or higher for wear resis-tance and strength. Multi-pump Ratio Capability - outer drive gear allows multiple Pumps to be driven at di erent gear ratios by a single to provide stable, precise, repeatable ow control of process uids despite variations in temperature,viscosity, and pressure. The Zenith BMB/BMC Series pumpsare broadly applied to metering services such as colorings,catalysts, resins, avorings, perfumes, vitamins, oils,binders, adhesives, coatings, inhibitors, paints/varnishes,polymers, lubricants, dyes, defoamers, pharmaceuticals,urethanes, fuels, viscose, and many others for the world stop industrial PumpsBMB/BMC SeriesPrecise Flow Control7335-CMB9935-BMBledoM(2-Gear Design)(3-Gear Design) , , )ver/cc()ver/cc(Flow GPH56-1008 cc/min111-5004 cc/minTemperature300 F (150 C)300 F (150 C)LimitRecommendedmpr 081-01mpr 081-01 Speed RangePump Rotation(Facing OuterWCCWCCD rive Gear)
