Installation, Oper ation & M aintenance M anual
TR-C Series Centrifugal Pump
ASSEMBLY PRELIMINARIES
Before beginning the assembly procedure, identify every element that is going to be installed.
You can use the exploded view and part list shown in pages 6 and 7. During the assembly
you may need the following tools:
1. 1", 3/4", 9/16" and 1/2" Wrenches.
2. 1/8", 5/32", 3/16" and 1/4" Allen wrenches.
3. Rubber mallet.
4. Caliper, useful when assemble seal type
“E”.
5. 5/8" & 7/8" Socket
– for impeller nut, for TR-C+ models.
6. 3/8" diameter steel rod
– to hold stub shaft plus, for TR-C+ models.
7. Torque Wrench
Recently, we have added new lines to the known TR-C series: the kit plus, TR-C plus series,
and IC plus series for every specific application. There are some modifications in the
assembly in each one of these series without altering the operation of the equipment.
KIT PLUS (KIT+)
It is made up by a stub shaft plus, a stub shaft collar, a shaft key, an impeller plus, an impeller
nut, and the front and back impeller gaskets. The collar may use one or two screws according
to the pump model. This assembly works the same as a standard assembly from the TR-C
series.
TR-C PLUS (TR-C+) SERIES
The TR-C plus series has been developed to facilitate and offer some advantages to the
assembly of the TR-C series pumps. TR-C plus series have a better subjection when
mounting the stub shaft onto the motor using a collar. The stub shaft plus is threaded and
offers a better assembly to the impeller by means of a key and a nut. It was designed to meet
3A regulations. An ordinary TR-C series pump can be turned into a TR-C plus series with a
Kit plus.
IC PLUS (IC+) SERIES
Series IC plus is a modality of the TR-C series plus and is intended for industrial purposes.
It uses an internal mechanical seal denominated
T21,
which lodges in an industrial back
plate. Because of this is industrial, it does not meet 3A regulations. No other type of
mechanical seal, like
“
D
”, “
DG
”, ”
E
” or “
F
” seals from the TR-C series, is compatible with the
IC plus series. An ordinary TR-C series pump can be turned into a IC plus series with a Kit
plus, an industrial back plate, and a mechanical seal type
T21
.
