Series
7100 - Features & Benefits |
|
|
|
|
|
- Bearings
Engineered for a minimum B-10 life of 100,000 hours. Grease lubricated
bearings are standard on most pumps with oil lubricated bearings optional
on most.
- Impeller
Adjustments
Shims between the upper face of the bearing frame and bearing retainer
allow a simple but effective method of maintaining impeller clearances.
Wear ring and pump life is enhanced when impeller clearance is optimized.
- Stuffing Box
The easily accessible stuffing box and split bronze gland make adjustment
or repacking a simple procedure. The proper box proportions and Teflon
seal cage design help ensure low temperatures and extended packing life.
(Bronze seal cage available.) Standard stuffing box dimensions allow
the use of a variety of optional mechanical seals.
- Shaft
and Shaft Sleeve
The AISI 4150 alloy steel pump shaft is protected from abrasion
in the stuffing box area by a hardened 400 series stainless steel shaft
sleeve. The hooked sleeve design effectively seals the shaft from the
pumped liquid.
- Seal Water Drain
A tapped drain at the lowest point on the stuffing box cover permits
continuous drainage of all leakage from the stuffing box.
- Impeller
The impeller is designed for optimum balance between efficiency,
solids handling and abrasion resistance. Multiple vane impellers are
available for each pump model.
- Casing
The casing is a one-piece design for smooth hydraulic flow and maximum
solids passage. Extra thick casting walls provide extended protection
against abrasion and corrosion. Back pull-out design allows removal
of the impeller and bearing frame without disturbing existing piping.
- Wear
Rings
Replaceable 400 series stainless steel rings protect the impeller
and suction cover from wear. Axial sealing permits impeller adjustment
to maintain proper clearance. Wear rings available in optional materials
and hardness ratings.

Additional
features not illustrated above:
- Pump Support
Feet
Vertical configured pumps (VPM and VOS) are designed for three-point
mounting at the pump casing. When the driver is to be coupled directly
to the pump (VPM), Morris' exclusive fabricated pedestal is mounted
directly on the pump feet. This places the motor's weight on the support
piers. No stress is "passed through" the pump casing. (Smaller
motors may also be pedestal mounted directly on the bearing frame.)
- Inspection Ports
A generous and smooth internally contoured inspection plate is provided
on the casing. Inspection ports may be optionally furnished in suction
elbow or suction spool piece.
- Flush Water
Rings (optional)
A series of holes in the suction cover wear ring allows water to
be continuously injected during pump operation. This water injection
flushes away abrasives and fibrous material, thus extending the wear
life of the wet-end components.
- Temperature
and Vibration Monitoring (optional)
A wide variety of temperature and vibration monitoring devices are
available. A conveniently located pump-mounted junction box can be supplied
to terminate the sensor conductors and facilitate connections to customer's
instrumentation system.
