RESIDENTIAL SUBMERSIBLE
EJECTOR SYSTEM
The primary function for which the Submersible Sewage Pump is
designed is the handling of sewage and other fluids containing
unscreened nonabrasive solids and wastes. In order to insure
a maximum of efficiency and dependable performance, careful
selection of pump size is necessary. Required pump capacity will
depend upon the number and type of fixtures discharging into
the sump basin, plus the type of facility served. The fundamentals involved in selecting a pump for a Water System can be
applied to selecting a Submersible Sewage Pump. By answering the three (3) questions concerning capacity, suction, and
discharge conditions we will know what is required of the pump
and be able to select the right pump from the catalog.
1. To simplify the selection of the proper size Submersible Sew-
age Pump, the general rule is to base the pump capacity on
the number of toilets the pump will be serving. This differs
from the selection of the proper pump for a Water System in
that question 1, “Water Needed” is reversed. How much liquid
do we want to dispose of rather than how much do we need?
The following chart will help determine pump capacity:
Sewage Selection Table
for Residential or Commercial Systems
Number of Bathrooms GPM
1 20
2 30
The above selection table takes into consideration other fixtures
which will drain only water into the sewage basin.
Therefore, pump capacity should not be increased for lavatories,
bathtubs, showers, dishwashers, or washing machines. When no
toilets are involved in the facility served, for example, a laundromat, the major fixture discharging waste should be considered.
In this case, the chart should read “Maximum Number of Washing Machines.”
In areas where drain tile from surrounding lawns or fields enters
the sump, groundwater seepage can be determined as follows:
14 GPM for 1,000 sq. ft. of sandy soil
8 GPM for 1,000 sq. ft. of clay soil
If the calculated groundwater seepage is less than one-fourth
of the pump capacity required based on the number of toilets,
the pump capacity should not be increased. Any seepage over
the allowed one-fourth should be added to the required pump
capacity.
2. Since the pump is submerged in the liquid to be pumped,
there is no suction lift. Question 2 does NOT become a factor
in pump selection.
3. Answering Question 3, discharge conditions is the final step
in selecting a Submersible Sewage Pump. Only the vertical distance between the pump and the highest point in the
discharge piping, plus friction losses in discharge pipe and
fittings affect discharge pressure. (Friction losses can be obtained from the friction table in this Selection Manual.)
Normally service pressure is not a consideration. The total of
the vertical distance, plus the friction losses is the required
discharge head in feet.

To Calculate Flow with Fixture Counts
Take total number of each style fixture X Count for that fixture.
Add all fixture total counts. Add Full Body shower flow rate to
total.
Use “Hunter” estimate curves for Demand Load for appropriate
style fixtures. (Valve style fixtures are predominant in Commercial
buildings; Tank style fixtures are predominant in Residential).

Head Calculation
Example: Fig. 1. A two-bathroom home is situated such that
the city sewer main is located above the basement drain facilities. Groundwater seepage through drain tile into the sump is
estimated at 6 GPM. The vertical distance from the pump to the
highest point in the discharge piping is 12 feet.
A pump capable of pumping 30 GPM is required (seepage is
less than one-fourth of the pump capacity so it is automatically
included). The discharge head must be 12 feet, plus any friction
loss in the approximately 15 feet of pipe, 3-90º elbows, 3-45º
elbows, and check valve.
Assume plastic pipe is used.
1. RATE OF FLOW = 30 GPM
Two (2) toilets, includes seepage up to one-fourth of
selected
7.5 GPM allowable so no correction is necessary.
2. SUCTION CONDITIONS – Flooded Suction
3. DISCHARGE CONDITIONS
Vertical Differential 12.0'
Friction losses @ 30 GPM
15' of 2" pipe (1.8' per 100' of pipe) = .2' F.L.
3-2", 90º elbows = 16.5 equivalent feet
3-2", 45º elbows = 7.5 equivalent feet
1-check valve = 19.0 equivalent feet
Total = 43.0 equivalent feet = .6' F.L.
Total Discharge Head = ___________________ 12.8'
Referring to the catalog, we find that a 1/3 HP Sewage Pump
should be adequate for the job.

pump capacity. 6 GPM is less than the
Example: The same conditions as in the previous example exist,
except the house is located on a large tract of sandy soil where
the groundwater seepage is estimated @ 20 GPM.
1. RATE OF FLOW = 30 GPM
Two (2) toilets, includes seepage up to one-fourth of
selected pump capacity – 7.5 GPM.
The additional 12.5 GPM (20-7.5) must be added to
the required pump capacity – 12.5 GPM
Total = 42.5 GPM
2. SUCTION CONDITIONS ____________Flooded Suction
3. DISCHARGE CONDITIONS
Vertical Differential – 12.0'
Friction losses @ 42.5 GPM
15' of 2" pipe (3.5' per 100' of pipe) = .5' F.L.
3-2", 90º elbows = 16.5 equivalent feet
3-2", 45º elbows = 7.5 equivalent feet
1-check valve = 19.0 equivalent feet
Total = 43.0 equivalent feet or 1.5' F.L.
Total Discharge Head = 14.0'
Referring again to the catalog, we find that a 1/3 HP
Sewage Pump should be adequate for this installation.

A minimum of 24" is required for simplex. Duplex stations
normally start at 36", but require much larger for larger diameter discharge pumps.
For example: A pump that flows 100 GPM, requires a 2-minute run time. A duplex station with a diameter of 36" holds
4.4 gallons (see Chart A) per inch.
50 GPM x 2 minutes = 100 gallons
100 gallons / 4.4 gallons per inch 22.72" for pump down.
22.72" would be used for (E).

AGENCY LISTINGS AND POWER CORD PLUG REMOVAL
Our single-phase sump, effluent and sewage pumps with 115,
208 and 230 volt motors up to and including 1 HP are now
built with NEMA three-prong grounding plug power cords. This
allows qualified electricians or professional pump installers to
easily connect the pumps; according to U.S. National (NEC),
Canadian (CSA), state, provincial and local electrical codes, to a
properly rated piggyback float switch for automatic operation.
NOTICE: This statement is written for the intent purpose of
verifying to electrical inspectors that according to both UL and
CSA standards it is allowable to remove the plug ends for direct
wiring to a disconnect switch, control panel or hard wired float
switch. Removing the plug end does not violate our UL Listing
or CSA/CUS certification in any way. Always follow the aforementioned codes when making connections to the bare leads
once the plug is removed. Plug removal information and wiring
diagrams may be found in the Installation Manual supplied with
the pump and in this booklet. Please use this statement in the
event an inspector needs written assurance of this policy.

Application – Three Phase Unbalance
THREE PHASE POWER UNBALANCE
Red Jacket Water Products, CentriPro
A full three phase supply is recommended for all three phase
motors, consisting of three individual transformers or one three
phase transformer. So-called “open” delta or wye connections
using only two transformers can be used, but are more likely to
cause problems, such as poor performance overload tripping or
early motor failure due to current unbalance.
Transformer ratings should be no smaller than listed in Table 2
on page 3 for supply power to the motor alone.
Checking and correcting rotation and current unbalance
1. Establish correct motor rotation by running in both directions.
Change rotation by exchanging any two of the three motor
leads. The rotation that gives the most water flow is always
the correct rotation.
2. After correct rotation has been established, check the current
in each of the three motor leads and calculate the current
unbalance as explained in 3 below.
If the current unbalance is 2% or less, leave the leads as connected.
If the current unbalance is more than 2%, current readings
should be checked on each leg using each of the three possible hook-ups. Roll the motor leads across the starter in the
same direction to prevent motor reversal.
3. To calculate percent of current unbalance:
A. Add the three line amp values together.
B. Divide the sum by three, yielding average current.
C. Pick the amp value which is furthest from the average cur-
rent (either high or low).
D. Determine the difference between this amp value (furthest
from average) and the average.
E. Divide the difference by the average.
Multiply the result by 100 to determine percent of
unbalance.
4. Current unbalance should not exceed 5% at service factor load
or 10% at rated input load. If the unbalance cannot be corrected by rolling leads, the source of the unbalance must be
located and corrected. If, on the three possible hookups, the
leg farthest from the average stays on the same power lead,
most of the unbalance is coming from the power source. However, if the reading farthest from average moves with the same
motor lead, the primary source of unbalance is on the “motor
side” of the starter. In this instance, consider a damaged cable,
leaking splice, poor connection, or faulty motor winding.

To reverse rotation, interchange any two leads.

Determining Flow Rates
FULL PIPE FLOW – CALCULATION OF DISCHARGE RATE USING HORIZONTAL OPEN DISCHARGE FORMULA
An L-shaped measuring square can be used to estimate flow
capacity, using the chart below. As shown in illustration, place 4"
side of square so that it hangs down and touches the water. The
horizontal distance shown “A” is located in the first column of
the chart and you read across to the pipe diameter (ID) to find
the gallons per minute discharge rate.

Variable Speed Drives
WASTEWATER PUMPS AND VARIABLE SPEED DRIVES
Goulds Water Technology, Bell & Gossett,
Red Jacket Water Products, CentriPro
It is acceptable and increasingly more common to operate threephase wastewater pumps using VFD’s or variable frequency
(speed) drives. We have successfully tested and operated all our
premium cast iron construction, three-phase pumps between 30
and 60 hertz operation. The pumps should never be operated
below 30 hertz (the VFD must be programmed for a minimum
speed of 30 hertz to prevent continuous operation) or above 60
hertz due to increased motor HP loading, higher amperage and
the resultant heat rise (see HP in 70 hertz Performance Multipliers).
The “Affinity Laws” state that for a given pump, the capacity will
vary directly with a change in speed, the head will vary as the
square of the speed change and the required power will vary as
the cube of the speed change. (The Affinity Law formulas can be
found in the Water Products Technical Manual, TTECHWP). The
Performance Multiplier Chart provides shortcut multipliers that
eliminate having to solve the Affinity Law equations.
To calculate a pump’s total performance range when using a
VFD, use the 30 hertz data to create a minimum speed curve, the
VFD controlled pump should always be operated between 30
hertz and the published 60 hertz curve. Where it operates at any
given moment is irrelevant.
Q1, H1 and BHP1 are determined at the pump’s rated speed
N1 (rpm).
Q2, H2 and BHP2 are determined at speed N2 (rpm).
Hertz Performance Multipliers
70 – Q2 = Q1 x 1.17 H2 = H1 x 1.37 BHP2 = BHP1 x 1.6
60 – Use the standard published curve data
50 – Q2 = Q1 x .83 H
40 – Q2 = Q1 x .67 H2 = H1 x .45 BHP2 = BHP1 x .3
30 – Q2 = Q1 x .5 H2 = H1 x .25 BHP2 = BHP1 x .125
An example would be, solve for Q2, H2 and BHP2 for a 60 Hz
pump that produces 100 gpm (Q1) @ 100’ tdh (H1) using 5 hp
(BHP1) when it is operated at 30 Hz :
Answers: 100 gpm x .5 = 50 gpm, 100’ TDH x .25 = 25’ TDH
and 5 hp x .125 = .63 hp.
VFD’s save energy while reducing the thrust on the motor bearings and the starting torque on the shaft and impeller.

our full line of VFD products.

Use the multipliers with a minimum of 3 data points taken from
any standard, 60 Hz curve to determine the performance of that
pump at a new speed.

Sewage Control Panels and Switches
There are two basic switches used in sewage and effluent systems. Single-action or narrow-angle float switches perform one function
(on or off). They operate over a range of 15º. Wide-angle, or double-action float and diaphragm switches perform two functions (on
and
off). Wide-angle float switches operate over a 90º range and diaphragm switches on a 6” rise in water level.
Control panel wiring diagrams refer to 3 float and 4 float systems, this terminology refers to the use of single-action switches. The following chart shows how many of either type switch to use with different control panels.
Duplex Control Panels
Typical Duplex panels use the following switch set-ups depending on the switch type you use. Most Duplex control panels have a standard high level alarm circuit with a flashing light, most have a horn or bell. Once it turns On - the alarm must be manually reset (turned
off) on Duplex panels.
Using a Single-action or Narrow-angle Switch requires:
Three Float Panel Wiring Four Float Panel Wiring
#1 Bottom Pumps Off #1 Bottom Pumps Off
#2 Middle 1st Pump On #2 2nd 1st Pump On
#3 Top 2nd Pump & Alarm On #3 3rd 2nd Pump On
#4 Top Alarm On
Using Double-Action or Wide-Angle Switches; A2D23W, A2E21, A2E22, A2E23,
A2D11, A2D31 or A2S23 requires:
Three Float Panel Wiring Four Float Panel Wiring
#1 Bottom 1st Pump On/Both Off #1 Bottom 1st Pump On/Both Off
#2 Top 2nd Pump and Alarm On #2 Middle 2nd Pump On
#3 Top Alarm On
Simplex Control Panels
Only some Simplex panels have alarms. This is why the switch quantity requirements vary by simplex panel model.
All of our SES panels have high level alarms.
Using a Single-action or Narrow-angle Switch requires:
Simplex Panel with Alarm Simplex Panel with No Alarm
#1 Bottom Pump Off #1 Bottom Pump Off
#2 Middle Pump On #2 Top Pump On
#3 Top Alarm On/Off
Using Double-Action or Wide-angle Switches requires:
Simplex Panel with Alarm Simplex Panel with No Alarm
#1 Bottom Pump On/Off #1 Bottom Pump On/Off
#2 Top Alarm On/Off
NOTE: 1st pump may also be referred to as “Lead” pump,
2nd pump may be called “Lag” pump.
