Zenith BPB Series pumps allow dependable control of
critical process streams or additives. High accuracy eliminates costly
overdosing associated with less accurate methods, and the pumps often pay
for themselves in savings in one year or less. Concentrated solutions can
be precisely metered pulse-free without dilution.
Applications
Designed to provide stable, precise, repeatable flow control of process
fluids despite variations in temperature, viscosity, and pressure. The
Zenith BPB 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.
