TECHNICAL INFORMATION

THE RIGHT CHOICE

The Myers® high head 7 1/2, 10 and 15 HP submersible centrifugal grinder pumps are designed for municipal, commercial or industrial applications. These pumps are especially suited for use in pressure sewer applications or in systems with long discharge runs or high static heads. The pumps feature a heavy-duty cutter mechanism and recessed impeller designed to efficiently grind typical sewage solids into a fine slurry.

The grinder pumps are available in standard and FM Listed hazardous location construction for use in Class 1, Groups C & D hazardous locations.

Pentair's line of Myers grinder pumps can be installed in a variety of packaged systems. Factory-assembled simplex or duplex packages with guide rail systems are available. Individual rail components are also available for installation in on-site concrete systems. Pentair offers a complete line of submersible sump, sewage, effluent, grinder, solids handling wastewater pumps, controls, basins and accessories. For additional information, please contact your local sales representative or the sales office at 419-289-1144.

IDEAL FOR USE IN PRESSURE SEWER SYSTEMS.

• Recessed impeller provides steep non-overloading operating curve.

DURABLE MOTOR WILL DELIVER MANY YEARS OF

RELIABLE SERVICE.

• Oil-filled motor for maximum heat dissipation and constant bearing lubrication.

• Recessed impeller reduces radial bearing loads; increases bearing life.

• High-torque three phase motors for assured starting under heavy load.

• Seal leak probes and on-winding heat sensors warn of seal leak condition and stop motor if motor overheats. Helps prevent costly motor damage.

DESIGNED FOR EASY MAINTENANCE.

• Shredding ring and grinder impeller are replaceable without dismantling pump or motor.

ADVANTAGES BY DESIGN

CABLE ENTRY SYSTEM

Provides double seal protection.

Cable jacket sealed by compression grommet. Individual wires sealed by epoxy potting.

HEAVY 416 SST SHAFT

Corrosion resistant. Reduces shaft deflection due to grinding loads.

STATOR

3450 RPM, 3 phase. Press fit for perfect alignment and best heat transfer. Oil-filled motor conducts heat and lubricates bearings.

Class H, VFD.

SHAFT SEALS

Double tandem mechanical shaft seals protect motor.

Oil-filled seal chamber provides continuous lubrication.

SEAL LEAK PROBES

Detect water in seal housing. Activates warning light in control panel.

(Test resistor on FM listed pumps only.)

VOLUTE CASE

Cast iron; horizontal discharge.

(Drilled for 2½" pipe flange.)

GRINDER ASSEMBLY

Grinder impeller and shredding ring are replaceable without dismantling pump.

Constructed of 440 SST hardened to 58-60 Rockwell.

HEAT SENSOR

Protects motor from burnout due to excessive heat from any overload condition. Automatically resets when motor has cooled.

BALL

BEARINGS

Upper and lower ball bearings support shaft and rotor and take axial and radial loads.

IMPELLER

Ductile iron recessed impeller handles ground slurry without clogging or binding.

Provides unobstructed flow passage. Reduces radial loads. Pump-out vanes help keep trash from seal; reduces pressure at seal faces.

SLEEVE

BEARING

Takes radial shock load;

provides flame path.
