Features
Pump Impeller Is recessed
type — operates completely
out of volute passage giving
full opening for flow of liquids
and solids.
Motor Housing is heavy cast
iron. Stator is pressed in for
perfect alignment, best heat
transfer.
Powerful 4/10 HP Motor is
oil filled for good insulation and
lubrication of bearings and seat.
Overload protection built-in, has
no starting switch or relay
mechanism.
Thrust Washers and Sleeve
Bearings are oil lubricated for
smooth operation, long pump life.

SITE EVALUATION REPORT
FOR PEGGY PITMAN
OF LOT 2, BLOCK 1, JANET ACRE
ORONO, MINNESOTA
�odIE
UDEC 2 7 M
Additional information follows for the design of a pressure
mound system needed for the above property. In addition, two septic
tanks of at least 1000 gallons are needed and a third pumping tank
of at least 750 gallons is required to house the pump. An alarm de-
vice should be used to warn of pump failure.
All construction and materials must adhere to the provisions
of the City of Orono. No grading or construction traffic is permit-
ed on both the primary and the alternate drainfieId sites. Runoff
water must 5e diverted from the mound area.
If any other information is n?eded, please contact me.
Sincerely,
PERCOR. INC.

PUMP SELECTION PROCEDURE
A. Determine pump capacity:
I.
Minimum suggested is 600 gallons per hour (10 rpm) -
to stay ahead of water use rate
2.
Maximum suggested for delivery to a drop box of :i home
system is.2700 gallons per hour (45 gpm) to prevent
buildup of pressure in drop box
3.
Use value from design of pressure distribution system
