1.0 INTRODUCTION

This manual contains information important to the installation, operation and maintenance
of your Tonkaflomulti-stage centrifugal pump. Your Tonkaflo pump has been designed for
reliable service in many types of pumping applications. Proper installation and normal main­tenance will help ensure extended pump life and prevent costly downtime.

Before installing and operating your Tonkaflo pump, please read these instructions carefully
and keep this manual handy for future reference. This manual is intended for general main­tenance only.

Further information may be obtained by contacting your nearest Tonkaflo distributor or GE.

This manual is not int

ended for repair or overhaul of the Tonkaflo pump liquid ends.

Only the factory and those certified by the Factory Service School are authorized to repair,
service or overhaul Tonkaflo liquid ends.

Your new Tonkaflo multi-stage centrifugal pump is designed for quiet, efficient, vertical oper­ation in environments where noise from a fan-cooled motor is acceptable. A modular design
permits the liquid end to be separated from the motor module for greater serviceability, while
at the same time ensuring precise shaft alignment. The materials and construction of Quiet
Submersible Verticle (QSV) pumps make them suitable for many chemical and pure water
applications.

The Tonkaflo pump’s multi-stage design allows the user to choose a pump model that most
closely matches the desired performance and, thereby, to achieve the highest pumping effi­ciency. Unlike many other pump manufacturers, Tonkaflo will produce pumps to fit your par­ticular applications should a standard model not suit your requirements.

2.0 TONKAFLO SPECIFICATIONS

2.1 Pump Label Nomenclature

All Tonkaflo pumps use the same model number nomenclature to describe the
series name, nominal flow rate, staging and operation of the pump.

The pump label, showing model number, serial number, construction and
performance, is located immediately downstream from the electrical junction box on
the top side of the liquid end shell. The motor label, showing horsepower, voltage, Hz,
rated amp draw, service factor and service factor amps (S.F.A.), is located immediate­ly upstream from the junction box on the top side of the motor module.
Figure 2.1 (Pump Label and Motor Label) shows these locations.

Summary

Standard model pumps shown. Higher pressures are available upon request.

2.2.2 All QSV Pumps - IMPORTANT!

There is no limit on pumping capacity when operating QSV pumps in parallel.
The discharge pressure of your QSV pump may be increased by 100 psig (6.9
barg) by connecting another pump in series ahead of the QSV pump. Care
must be taken, however, so that the inlet pressure to any QSV pump does not
exceed the 100 psig (6.9 barg) maximum inlet pressure rating.

There must be adequate flow through the pump at all times to prevent exces­sive heat build-up.

3.0 PUMP INSTALLATION

3.1 Inspection

Your pump was inspected and tested at the factory prior to shipment to ensure it
meets the requirements of your order. It is suggested the pump be checked upon
receipt for possible damage due to shipping. Any damage should be immediately
reported to the carrier.

3.2 Pump Mounting and Locations

The QSV Series pumps are intended for vertical mounting with the right angle inlet of
the pump down. See Figure 2 for correct orientation. The weight of the pump and
motor must be supported by setting the flat end of the outer housing on a rubber pad
supported by a plate or angle. Attach the pump to the frame work of your system
using ALL brackets included. Refer to Section 8.0 (Dimensional Drawing) for correct
bracket placement.
