PUMP FEATURES:
The cast iron pump casing has a smooth waterway to insure maximum efficiency
when handling sewage. Rabbeted construction insures complete alignment of the
rotating element. The cast iron impeller is of non-clog design for handling
water containing solids, and is balanced prior to assembly. The vertical
discharge flange and gasket permit easy installation of plain-end discharge
pipe.
MOTOR FEATURES:
Motors are available for 1750, 1150 and 870 R.P.M. operation with both single
phase and three phase windings. Single phase motors are furnished with a
separate capacitor box. All motors have prelubricated ball bearings, are U.L.
listed for Class 1, Group D explosion-proof service.
They are rated for intermittent duty in air at full load, continuous duty in
air at reduced load, and, if furnished with modified frames, for continuous duty
in air at full load. Shaft and fasteners are stainless steel. End bracket and
frame are cast iron. All leads are epoxy sealed.
Double seals provide protection for the electrical parts. If the outer seal
fails, the inner seal protects the motor while water enters the oil-filled
chamber. A moisture sensing probe detects the entry of water into the chamber
and sends a signal to the appropriate alarm.
Motors are furnished with 25-feet of power and control cable and grounding
wire. The standard motors are rated for operation in 40°C (104°F) water, but
can be modified for higher ambient temperatures. Thermal protection is a
standard feature.
QUICK-DISCONNECT FEATURES:
Each pump is furnished with a Quick-Disconnect assembly so that it can be easily
lifted from the pit for inspection or service. Discharge piping and electrical
connections need not be disturbed and the removal can be accomplished without
anyone entering the sewage pit. The pump is lowered into the pit, held in
position by its guide rail and automatically completes the discharge connection.
The angled discharge mating flange is designed to assure a complete discharge
seal.
MODIFICATIONS AND ACCESSORIES:
Pumps can be furnished with bronze impellers, stainless steel fasteners, longer
cables and special seals. Accessory items include moisture detection relays,
motor controls, high water alarms, steel covers and grouting frames or hinged
access doors for concrete pits and steel, cast iron or fiberglass receiving
basins.
Fed-Flush strainer fittings are also available with VSS-QD systems (see
VSSF-QD Bulletin 236).
CONTROLS:
The recommended control arrangement for VSS-QD pumps is the Submers-a-bulb
control (see SBS Bulletin 263) which includes on-off mercury bulbs, high water
alarm, temperature sensor cut-out, moisture sensor alarm and automatic
alternator for duplex units.
Float switch controls are also available.

DIMENSION NOTES:
1. All dimensions are in inches unless otherwise noted.
2. Dimensions shown are not to be used for construction purposes unless
certified.
3. Pit sizes and opening sizes are minimums. Actual sizes must be determined by
job conditions.
4. Guide rails must be installed in perfectly vertical position. Use plumb line
to correctly position the pump base.
5. Pump discharge check valves and gate valves should be installed on horizontal
or 45° lines. Installation on vertical lines is not recommended.
6. The VSS-QD guide rail is an ASTM Std. 4" wide-flange beam (4"
H-column).
