Flowserve Frame mounted Pumps
Flowserve PolyChem S-Series Fluoropolymer Lined Mechanically Sealed Pumps

Revolutionary Non-Metallic Pump Technology

Flowserve fluoropolymer lined sealed pumps offer outstanding performance and significant economy in highly corrosive applications. Incorporating the proven Mark 3 power end, PolyChem S-Series pumps are engineered to maximize performance and reliability.

Addressing customer needs around the globe,

PolyChemS-Series pumps meet the following dimensional standards:

● ASME B73.1

● ISO 2858/5199

● JIS drilling

FEATURES

Operating Parameters:

• Flows to 420 m3/h(1850 gpm)
• Heads to 145 m (480 ft)
• Pressures to 17 bar (250 psi)
• Temperatures from -30°C(-20°F) to 150°C (300°F)
• External Micrometer Impeller Adjustment accurately sets impeller in 20 seconds. Furthermore, mechanical seals and all critical settings can be set accurately in the shop. Fluoropolymer PFA Lined Wet End is globally preferred for its superior corrosion resistance and temperature allowance.
• Enclosed Impeller, through 250 mm (10 in), provides balanced hydraulic loads, extending bearing life. Open impeller available.
• Clean Room Assembly of optional ANSI 3A™ power end ensures optimum lubrication environment. Mark 3 power end is standard.
• Silicon Carbide Shaft Sleeve mitigates corrosion and wear.
• Seal Chamber with large tapered bore accommodates multiple seal selections

Advanced FM SealSentry™ Design Technology:

• Only Flowserve offers a non-metallic pump with the advantages of an oversized seal chamber with flow modifiers.
• Self-flushing
• Self-venting
• Self-draining
• Seal life is extended due to superior purging of heat, solids and vapors. Costs are reduced because single seals often can be selected where dual seals or external flush and throat bushing combinations had been necessary.
• Flow Modifiers Extend Mechanical Seal Life
• Redirect flow from circumferential to axial.
• Balanced flow with low pressure drop in the chamber keeps solids in suspension, minimizing erosion.
• Mechanical seal creates a centrifuging action away from its parts and into the returning flow path of the process liquid.
• Solids and slurry merge into the returning flow path and are flushed out of the seal chamber.
• High flow rate prevents suspended solids from precipitating or crystallizing on the seal or seal chamber.
• Unique Seal Chamber Canister allows double component seals to be applied in the FM seal chamber. This canister enables quick retrofits and eliminates the need to stock additional rear covers.
