CHEMSTEEL SERIES R102 METALLIC
PERFORMANCE
A full range of accessories
are available including:
• close coupled mounting kits
• baseplate/pedestal mounting kits
• line mounted pressure relief valves
GENERAL DESCRIPTION
Chemsteel pumps are designed to handle common and highly
corrosive liquids that must be pumped under pressure.
Manufactured to extremely precise tolerance, the Chemsteel
pump line prevents system contamination while maintaining the
purity and integrity of the liquid being pumped. Its rugged, threesection, o-ring sealed thru-bolt construction provides ease of
servicing and parts replacement. Helical gearing offers noise
reduction by as much as 10db, while the tandem pumps double
the output flow for a single fluid, or with isolation, handle
other fluids in direct ratio to the first. Additionally, Chemsteel
pumps offer bi-directional operation for applications requiring
reversing flow.
LIFE CYCLE/COST OF OWNERSHIP
Pump design and materials selection,together provide the
longest life available from a gear pump.
Key attributes include:
- Gear & bearing combinations of metallic
and nonmetallic wear surfaces.
- Slotted bearings to lubricate shaft and gear surfaces.
- Hydraulic porting to balance axial thrust
and to reduce wear.
- Ample port sizing to reduce the likelihood of
cavitation when inlet pressure is marginal.
- Effective housing seals with elastic memory
prevent leakage of corrosives.
SPECIFIC SOLUTIONS
Gear/bearing design allows for “trimming” for optimizing the
pump’s maximum flow to reach minimum turndown or to match
flow to a specific OEM’s requirement.
Special materials combinations are available for specific liquids:
- Stainless or Alloy C housing construction.
- Gears available in 316 stainless, Alloy C.
Also in Teflon®, and PEEK®.
- Shafts are 316 stainless steel or Alloy C.
- Bearings available in carbon or Teflon®.
- Full range of seal options including lip seal, packing
and mechanical designs.

Notes: For continuous service:
Plastic / Plastic gear combinations are limited to 50 psi.
Metal / Plastic gear combinations are limited to 100 psi.
FIT
Connections are 1/4“ female NPT or BSPT, pump hardware is
metric and close couple adapters mount to both NEMA and IEC
standard motor frame sizes for world wide acceptance. “Near”
dimensional interchangeability offers easy upgrade to Chemsteel
pump. The port size is the same as competitive pumps.

MAINTENANCE
A three-part housing provides easy disassembly and
service. Full size bearings match the gear diameter, and
eliminate the need for separate wear plates. TFE encapsulating silicone o-ring pump housing seals provide elastic memory to assure an effective long lasting seal and
thus avoiding the re-torquing required of pumps using
pure TFE. The upper shaft configuration lends itself to
in-line pump seal maintenance without the leakage of
trapped chemicals from an incompletely drained pump.
