Zenith's B-9000 Series precision metering
pumps utilize rotary, external spur gears which dispense an exact volume
of fluid per shaft revolution (cc/rev). Precision ground and
lapped construction and alignment dowels allow for close control of
operating clearances. This ensures precise, pulseless, and repeatable flow
under varying process conditions. Integrated closed loop speed
control and a compact motor driver system maintain set point speeds to .01%
and also accept automated interfaces.
The
B-9000 Series is constructed of 440C stainless steel which provides
excellent wear resistance (hardness 54 Rc) and corrosion resistance for
most chemical processes. The pump offers increased uptime while minimizing
maintenance due to its simple design of only three moving parts.
The B-9000 Series is a new generation of Zenith’s traditional B-Series
metering pump. While maintaining precise flow characteristics, its optimum
gear design reduces bearing loads, extending speed capability. The pump
allows direct piping and shaft engagement. A single mechanical shaft seal
eliminates sealing concerns. The pump complies with European Community and
DIN standards.
For years, engineers have relied on Zenith to provide precision fluid
handling solutions for their most difficult pumping applications. Zenith
gear pumps can be found wherever precise, pulseless, and repeatable
metering of fluids is required.
Stable, repeatable flows are assured even
under varying conditions of temperature, viscosity, and pressure.
Minimum Pulsation - Unique design offers virtually pulseless flow
without valves or flexible elements to hinder performance.
Low Cost of Ownership - With only three moving parts and 400 series
stainless steel construction, the pump provides corrosion resistance for
most chemical processes, and it is through hardened to 54 R c or better for
maximum life.
Precision Construction - Ground and lapped components allow for
operating clearances to .00015" and provide high volumetric
efficiency.
Active Flowmeter Concept - Unparalleled mechanical precision,
combined with the closed loop set point accuracy, ensures an exact volume
per revolution without expensive flow meters.
Experience - Zenith has over 75 years of application experience
with engineers available 24 hours a day to support your precision fluid
metering needs.
