APPLICATIONS

Heavy duty design features for a wide range of

commercial and industrial applications such as:

• Sewage systems

• Flood and pollution control

• Industrial dewatering

• Wastewater treatment plants

• Municipal and subdivision lift stations

SPECIFICATIONS

Pump:

• Solids handling capabilities: 3" maximum.

• Discharge size: 4" 125# ANSI anged.

• Capacities: up to 1160 GPM.

• Total heads: up to 140 feet.

• Minimum ow: 100 GPM.

• Maximum ow: end of published curve.

• Mechanical seals: 304 stainless steel metal parts,

BUNA-N elastomers with carbon/rotary and

ceramic/stationary faces standard for upper and

lower seals. Optional lower seals are available with

Viton elastomers and either silicon carbide/silicon

carbide or silicon carbide/tungsten carbide faces.

• Fasteners: 300 series stainless steel.

Motor:

• CSA certied motors (Canadian Standards

Association)

• Three phase motors only

• Available voltages: 200, 230, 400, 460 and 575 volt,

60 Hertz

• HP Range: 7.5 - 40

• Motor shaft is a one-piece design of high strength

416 stainless steel

• All motors are air-lled and designed for continuous

duty when fully submerged or for up to 15 minutes

operation in air.

• NEMA design “B” with copper windings

• Class “F” stator winding designed for inverter duty

• Moisture System: Two wire dual probe monitoring

system constantly monitors seal oil chamber and

stator housing for moisture. Note: control panel

must contain an alarm circuit and alarm device.

• Two (2) normally-closed, automatic reset thermostats

connected in series and embedded in adjoining

phases.

• Power and sensor cords are 25’ standard length, 50’

available as an option.

• Motors conform to the latest applicable

requirements of NEMA, IEEE, ANSI and NEC

standards.

NOTICE: Class 10 quick trip overload protection must

be provided in control panel.

AGENCY LISTINGS

FEATURES

Impeller: Cast iron, two vane closed design for high efcien-

cy and maximum wear life. Balanced for smooth operation.

Optional bronze impeller available.

Bronze Wear Ring: Replaceable to renew the running clear-

ances and efciencies to original conditions.

Casing: Heavy duty cast iron, volute type for maximum ef-

ciency. 4" 125# ANSI cast iron anged. Adaptable to guide

rail mounting system.

Tandem Seals: Two independently mounted mechanical

face type seals are separated by an oil lled chamber. The

oil chamber acts as a barrier to trap moisture and provide

time for a planned shutdown and maintenance. The oil pro-

vides lubrication to the internal (upper) seal. Carbon rotating

and ceramic stationary faces are standard on both internal

(upper) and external (lower) seals. Optional materials are

available for the lower seals. See the Nomenclature Page for

order number changes to order either silicon carbide/silicon

carbide faces with Viton or silicon carbide/tungsten carbide

faces with Viton elastomers. These are recommended for

applications containing ne solids or abrasives as found in

parking lot/garage drainage and construction dewatering

jobs.

Moisture Protection System: Two-wire, dual moisture sens-

ing probes are located in the oil lled chamber between the

inner and outer seals. When connected to a control panel

with an optional Moisture Detection System and an alarm it

will detect the presence of moisture should the outer seal

fail. It will also detect moisture in the motor chamber and

provide a warning prior to water levels reaching the bearing

or stator.

Designed for Continuous Operation: Motor is rated continu-

ous duty submerged condition in water that is 40º C or be-

low. Maximum runtime with pump unsubmerged for 7½–40

HP is 15 minutes. Motor is suitable for 10 starts per hour.

Bearings: Ball, single-row, angular contact, Conrad type

bearings with a Class 3 internal t conforming to AFBMA

Standard 20 are used. The bearings are greased for life with

a premium moisture resistant polyurea thickened grease

containing rust inhibitors and suitable for operation over a

range of – 25º C to + 120º C.

Impeller Mounting Screw: 300 series stainless steel with

anti-rotational locking patch.

Castings: All iron castings are ASTM A48 class 30 gray cast

iron. Optional bronze impeller is ASTM B584 C87600 silicon

bronze.
