Pierce-Roberts
Rubber in the Air and Fluid Control
Industry
Pierce-Roberts specializes in the
strict sizing and tolerance applications
necessary for the air and fluid control
industry. Pierce- Roberts rubber products
are meticulously inspected to assure
precision and quality.
Rubber Sanitary Gaskets
Rubber sanitary gaskets prevent leaks
in pipeline systems for the food,
dairy, beverage, pharmaceutical, and
biotechnology industries. Pierce-Roberts
provides elastomers for different
sanitary rubber gasket applications.
Less likely to adhere to equipment
fittings and lines, our rubber sanitary
gaskets have the lowest compression
set. Eliminate loss of product, improve
quality control, lower costs of frequent
replacements, and reduce downtime
and labor costs.
Molded Rubber Poppets
A poppet is part of an intake or exhaust
valve that plugs and unplugs its opening
by axial motion. Pierce-Roberts molded
rubber poppets control the flow of
fluid in heart valves, piston engines,
internal-combustion engines, etc.
Cylinder head design and fuel or air
flow speed are critical to engine
performance. Pierce-Roberts designs
superior poppets to exact specifications
for rapid air and fluid flow.
Rubber Diaphragms
Pierce-Roberts rubber diaphragms serve
as a barrier between two chambers
or as a device that vibrates when
certain frequencies are applied. Typical
design varies air pressure on one
side and fluid on the other. The fluctuations
in volume alternately force fluid
in and out of the chamber.
Pierce-Roberts molded rubber diaphragms
are tough, versatile seals that eliminate
most limitations associated with other
sealing methods. Applications include
actuators, regulators, valve, pumps,
accumulators, etc.
Molded Rubber Pump Housings
Pierce-Roberts rubber gaskets, plunger
caps, rubber suction hoses, and impellers
resist corrosion, abrasion, and breakdown
chemicals such as pesticides and organic
solvents. We use the correct rubber
compound that takes into account initial
pump cost, pressure, GPM (gallons
per minute) and volume, priming, and
available power. Applications include
rolling or rotary pumps with rolling
vanes and piston or diaphragm pumps.
