CHEMSTEEL SERIES S105 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
FEATURES:
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, three-section, o-ring thru-bolt
construction provides ease of servicing and parts
replacement.

Additionally, Chemsteel pumps offer bi-directional
operation for applications requiring reversing flow.
LIFE CYCLE/COST OF OWNERSHIP
Stainless housing construction.
Gears: Non-Galling Stainless Steel, Spur
Shafts:hardened 440C stainless
Bearings: Carbon
Mechanical Seal options available: A, B, C, J, Z
FIT
Connections are 1/2” 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.
Pump design and materials selection,together
provide the longest life available from a gear pump.
Key attributes include:
• 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.

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 inline pump seal maintenance without the leakage of
trapped chemicals from an incompletely drained pump.
