Zenith BLB Series metering pumps deliver precise,
pulseless, and repeatable flow control performance. Zenith precision metering pumps
greatly improve product quality while eliminating costly overdosing.
Applications
Designed to provide stable, precise, repeatable flow control of process fluids despite
variations in temperature, viscosity, and pressure. The Zenith BLB Series pumps are
broadly applied to metering services such as colorings, catalysts, resins, flavorings,
perfumes, vitamins, oils, binders, adhesives, coatings, inhibitors, paints/varnishes,
polymers, lubricants, dyes, defoamers, pharmaceuticals, urethanes, fuels, viscose, and
many others for the world's top industrial companies.
Benefits and Features
- High Accuracy -
Stable, repeatable flow control despite process variations of temperature, viscosity, and
pressure.
- High Pressure -
Precision manufacturing techniques hold tolerances to +.00005" (1.25 micron),
allowing gear clearances to be kept to a minimum and high process pressures to achieved.
- Pulseless -
Precise, rotary spur gears provide smooth, continuous, pulseless flow.
- Valveless -
Precision metering gears eliminate troublesome check valves used in reciprocating pumps.
- Active Flowmeter -
Unparalleled mechanical precision, combined with the closed loop Zenith ZeDrive™ 2000
controller ensures exact flow control without the addition of expensive
flowmeters.
- Long Life -
Only three moving parts - components through hardened to Rc-54 or higher for
wear resistance and strength.
- Multi-pump Ratio Capability -
Outer drive gear allows multiple pumps to be driven at different gear ratios by a single
motor.
