Custom Manufacturing High Precision Alumina Zirconia Ceramic
Metering Pump
Ceramic Pistons and sleeves in ceramic materials are a specialty of
Mingrui ceramic has been precision machining and polishing of ID's
and OD's allowing to meet the toughest customer requirements for
minimum clearance, seal-less metering pumps. Some designs in
alumina or sapphire achieve clearance of less than .0005" on
two-inch long travel. Other customer designs in polished quartz or
polished sapphire allow observation of combustion conditions for IC
engine research.
Mingrui is a precision machining company that fabricates parts from
all technical ceramics. They machine these materials to very
precise tolerances for dimension, also flatness, wedge, roundness,
and cylindricity, etc as required by their customers. They welcome
developmental parts as well as production requirements. Engineers
are available to discuss practicality of alternatives for your
application including material and cost drivers. See their website
for more information including available material properties with
an interactive Designer's Guide.

There are a variety of key advantages that come with ceramic
metering pump :
- Valveless Design The valveless feature of the Mingrui design is its
most significant feature. There are typically four check valves
present in diaphragm, bellows, and traditional piston pumps. Even
during normal operation, these will wear over time and not seal
properly allowing backflow. As a result, accuracy drifts and
minimally the pumps need recalibration. Eventually, the check
valves need to be serviced.
- Ceramic Internals The Mingrui uses sapphire-hard ceramics for both
the piston and mated liner. These components are dimensionally
stable in that they will not change shape or dimension over time.
Therefore, the pumping chamber remains stable for millions of
dispenses without downtime or recalibration. In addition to
dimensionally stable they are chemically inert which allows our
pump to work in a greater variety of chemicals.
- Accuracy & Precision Throughout the pumping cycle the inlet and
outlet ports of the Valveless Metering Pump are never interconnect
ensuring accurate fluid flow in one direction preventing any
backflow (without check valves). As a result Mingrui Ceamic is held from microliters to the full flow range and output does not
change more than ± 1% of set value. Inaccurate pumps can generate
waste and incur extra costs.
