B - SERIES SAMPLE
TSURUMI PUMP SEWAGE & WASTEWATER PUMPS SPECIFICATIONS

1. SCOPE OF SUPPLY -

Furnish and install TSURUMI Model _______________ Submersible Pump(s). Each unit shall be capable of
3
delivering _______GPM (_______m /min) at _______Feet ( _______m) TDH. The pump(s) shall be designed to
pump waste water, sewage or effluent containing _____ inch (_____mm) diameter solids without damage during
operation. The pump(s) shall be designed so that the shaft power required (BHP)/(kW) shall not exceed the motor
rated output throughout the entire operating range of the pump performance curve. The pump discharge size shall
Be____inch, (____mm).

2. MATERIALS OF CONSTRUCTION -

Construction of major parts of the pumping unit(s) including pump casing, impeller, and discharge elbow shall be
manufactured from gray cast iron, ASTM A48 CLASS 35. Unit(s) shall have a field adjustable and or replaceable,
cast iron shear type wear plate or wear rings. Internal and external surfaces coming into contact with the
pumpage shall be protected by a fused polymer coating. All exposed fasteners shall be stainless steel. All units
shall be furnished with a discharge elbow with 150 lb. (10 kg/cm2) flat face flange and NPT companion flange.
Impellers shall be of the solids handling design and shall be slip fit to the shaft and key driven. The pump casing
shall incorporate an air relief valve.

3. MECHANICAL SEAL -

All units shall be furnished with a dual inside mechanical shaft seal located completely out of the pumpage,
running in a separate oil filled chamber and further protected by an exclusionary oil seal located between the
bottom seal faces and the fluid being pumped. Units 2 Hp. and above shall be fitted with a device that shall
provide positive lubrication of top mechanical seal, (down to one third of the standard oil level). The device shall
not consume any additional electrical power. Mechanical seals shall rated to preclude the incursion of water up to
42.6 PSI. (98.4 Ft.). Units shall have silicon carbide mechanical seal faces. Mechanical seal hardware shall be
stainless steel.

4. MOTOR -

The pump motor(s) shall be _____Hp., _____ kW., _____V., 60 Hz., ___ Phase and shall be NEMA MG-1,
Design Type B equivalent. Motor(s) shall be rated at _____ full load amps. Motor(s) shall have a 1.15 service
factor and shall be rated for 20 starts per hour. Motor(s) shall be air filled, copper wound, class E, B, or F
insulated with built in thermal protection for each winding. Motor shaft shall be 420 or 403 stainless steel and
shall be supported by two permanently lubricated, high temperature ball bearings, with a B-10 life rating at best
efficiency point of 60,000 hours. On units up to 10 Hp. (7.5 kW), the bottom bearing shall be single row, double
shielded, C3, deep groove type ball bearings. On units 15 Hp. (11 kW) and above, the bottom bearing shall be
two row, double shielded, C3, deep groove type ball bearings. The top bearing on all units shall be single row,
double shielded, C3, deep groove type ball bearings. Motor housing and bearing housing shall be gray cast iron,
ASTM A48 CLASS 30. Motors shall be D.O.L. or Star-delta start (15 Hp. and above), and shall be suitable for
across the line start or variable speed applications, utilizing a properly sized variable frequency drive.

5. POWER CABLE AND CABLE ENTRANCE -

The pump power cable shall be suitable for submersible pump applications. Units up to 5 Hp., (except 150B63.7)
shall be supplied with a cable entrance that incorporates built in strain relief, a one piece, three way mechanical
compression seal with a fatigue reducing cable boot. On units 7.5 Hp. and above, and 150B63.7, the cable
entrance shall incorporate built in strain relief, and combination three way mechanical compression sealing with
a fatigue reducing/thermal expansion rubber boot. The power cable shall be field replaceable utilizing standard
submersible pump cable. The cable entrance assembly on all units shall contain an anti-wicking block to
eliminate water incursion into the motor due to capillary wicking should the power cable be accidentally
