WMTA Alloy Turbine Mag-Drive Pumps

Series WMTA

- Mag-Drive Single Stage Turbine

WMTA machined billet regenerative turbine sealless mag-drive pumps (superseding the MTA) can be constructed for high system pressures and special alloy configurations. All WMTA pumps are equipped with zero leakage magnetic couplings to meet the latest toxic emissions regulations. The absence of elaborate mechanical seal systems eliminates costly pump maintenance, lost production time and process contamination. Variations in head calculations have minimal effect on the flow of a turbine pump. Also, turbine pumps can be throttled to a required duty point without by-passing.

Features

High head/ low flow capability minimizes by-pass requirements and prevents overheating of centrifugals and high head cavitation
Self balancing impeller – Zero axial thrust loading
Impeller design handles up to 20% entrained gas-ideal for pumping liquefied gases
No galling or metal to metal contact
Heavy duty alloy containment shell
High torque magnets, suitable for direct starting motors

Technical Data

Flow: 25-45 GPM (.5-10 m³/H)
Head: To 700 feet (213 m)
Temperature Ratings: -148 to 600°F (-100 to 316°C)
Pressure ratings: 7250 PSI (500 Bar)

Materials

AISI SS-316 Stainless Steel, Alloy-20, Incoloy-825, Hastelloy-C27, *(Carbon Steel, Titanium, Casteloy)

WMPA P.D. Vane Mag-Drive Pumps

Series WMPA

Mag-Drive rotary Vane

The Warrender WMPA Machined Billet Rotary Vane Sealless Mag-Drive Pumps (superseding the WMDAV) are built for high system pressures and special alloy requirements. All WMPA pumps are equipped with zero leakage magnetic couplings to meet the latest toxic emissions regulations. The absence of mechanical seals eliminates costly pump maintenance, lost production time and process contamination. The WMPA pumps feature self-compensating sliding-vanes which maintain design head and flow capacities for extended operating life. The WMPA pumps are suitable for thin non-lubricating liquids and/or high differential pressures. The WMPA pumps are capable of dry self-priming.

Features

Self-priming and can run dry without damage
No gears to wear or metal to metal contact, low internal slip
Capable of proportioning with variable speed drives, turn-down ratios depend upon differential head requirements
Heavy duty alloy containment shell for added safety
Replaceable carbon cartridges-low maintenance costs
High Torque magnets for direct starting motors

Technical Data

Flow: .1-11 GPM (22-2500 m³/H)
Head: To 180 psig (12 bar)
Temperature Ratings: To 450°F (to 232°C)
Pressure ratings: 7250 PSIG (500 Bar)

Materials

AISI SS-316 Stainless Steel, Incoloy-825, Hastelloy-B or C-276

WMCH Billet PP/PVDF Mag-Drive Pumps

Series WMCH

Mag-Drive Centrifugal

WMCP machined thermoplastic horizontal centrifugal sealless mag-drive pumps (MCH Series) are fabricated from SOLID GLASS FREE Simona® PP or PVDF thermoplastics to resist internal or external corrosion. Heavy walled, CNC machined construction provide far greater resistance to permeation and migration of corrosive and permeating liquids. Additionally, added strength and thermal stability resists deformation, even in the most severe applications.

Features

Exclusive SOLID GLASS FREE machined PP or PVDF casings and impellers components for maximum chemical resistance.
All plastic casing withstands external corrosion
Integral raised face flanges (no threaded adapters) to ensure zero leakage
Modular impeller allows for varying hydraulic performances
Oversized, high purity ceramic or silicon carbide thrust bearings and shaft
Standard, direct starting NEMA motors

Technical Data

Flow: 3-500 GPM (.68-113 m³/H)
Head: To 175 feet (53 m)
Temperature Ratings: To 200°F (95°C)
Pressure ratings: 100 PSIG (7 Bar)
