Chemsteel Features

  • Mag drive sealless pumps eliminate the need for expensive mechanical seals; eliminating costly shutdowns and repairs, which helps reduce "Reportable Release" issues.
  • No maintenance intensive mechanical seals required. No seal flush or complex and expensive seal pot systems to monitor or maintain.
  • Straddle-mounted inner magnet system with bearings on both sides of the magnet - this design reduces shaft and bearing loads when compared to our competitors overhung, cantilevered, inner magnet designs
  • Slip-fit construction, which allows easy on-site maintenance with no special tools or fixtures required
  • Large internal flow paths, which means the pumps can easily handle 1% solids @ 500µ and up to 8% solids @ 100µ. Optional baffle-plated rear casing enables enhanced solids handling capability. Optional proprietary self-cleaning strainer technology enables us to handle even higher solids percentages if necessary
  • Safely handles toxic, noxious, corrosive or high-temperature liquids with increased safety to personnel and the environment
  • Special high-temperature construction is available to handle up to 800°F
  • Several dual containment systems are available that virtually eliminate any leakage to the environment when handling extremely hazardous chemicals

  • Flows from 0.5 to 30 GPM at 1750 RPM
  • Pressure from 0 to 150 PSI
  • 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.
  • Recirculation heat port versatility.
  • Containment can flush and drain connections.
  • 316 Stainless Steel
  • Alloy C
  • Non-Metallic - Ryton
  • Packing - Lip - Mechanical - Seal-less

NPT & BSPT porting Metric pump hardware Close-coupled adapters for NEMA and IEC standard motor frame sizes

Bi-Directional Operation

For applications requiring reversing flow

Body/Cover Static O-Rings

Teflon® encapsulating silicone for sealing with a memory

Combined Bearing ∓ Wearplate

Full size bearings match the gear diameter and eliminate the need for separate
wear plates Gear trimming for desired flow rates Made of carbon-graphite,
Teflon© or Rulon©

Helical Gears

Noise reduction up to 10 db

Extended Life

Gear & bearing combinations of metallic and non-metallic wear surfaces Slotted bearings to lubricate shaft and gear surfaces Hydraulic porting to balance axial thrust and reduce wear

Metallic & Non-Metallic

Wide range of capability Effective weight and cost selection

Dynamic Seal Options Include

Single or double mechanical wedge & bellows styles Standard compression packing Lantern Ring compression packing Lip seals

Chemsteel Tandem Pumps

Tandem Pumps double the output flow for a single fluid.

Or with isolation, handle different fluids in direct ratio to each other.

Mag Drive Catalyst Pumps

Chemsteel Magnetic Gear Pumps are engineered to safely handle hazardous, toxic, highly corrosive or explosive chemicals.

Available in: Stainless Steel, Alloy C and Ryton

Ryton©

Polyphenylene Sulfide PPS, an engineered, reinforced plastic, offering a wide range of chemical compatibility, physical stability, and high temperature resistance (to 200° F).

Type 316

An all purpose austenitic stainless, excellent corrosion resistance; premium choice of all 300 series alloys.

Alloy C

Most used of exotic high/nickel alloys. Superior corrosion resistance for severe alkaline and acidic pumping applications.

Gears

Precision machined metallic gears of 316SS, W88 stainless, and Alloy C. Also available in glass reinforced Teflon©, Ryton© and carbon reinforced PEEK.

Shafts

Shafts are 316 stainless steel or Alloy C.

Seals

Single and/or double mechanical seals are offered in elastomer bellows and Teflon© wedge designs. Bellows design available with Viton© or EPDM formed elastomer shaft seal. Wedge designs available with Teflon© wedge shaft seal and perfluoroelastomer stationary seat o-rings. Packing materials: Teflon©, Grafoil© and Teflon©/Graphite.

Body/Cover O-Rings

Teflon© encapsulating, silicone o-rings provide elastic memory to assure an effective long lasting seal. Avoiding the re-torquing required of pumps using pure TFE.
