1. INTRODUCTION
Eco Gearchem pumps are constructed in 316SS, Alloy 20 and Alloy C. Gears are available
in Alloy C, Alloy 20, glass filled TFE, Carbon/Graphite and PEEK. These pumps are used for
the reliable handling of clear lubricating and non-lubricating fluids. These pumps operate
over a broad range of temperatures, pressures and corrosive services for transfer
applications, cyclic operations or continuous production systems.
Self-priming Gearchem pumps can be operated over the entire pH range, for indoor and
outdoor service, at system pressures from as low as 1 mm Hg abs (vacuum) to 100 psi
differential pressure and over a temperature range from -100°F to + 450°F (-73°C to
+232°C). Gearchem pumps are available in flows up to 55 gpm and can be used to pump
liquids with viscosities ranging from less than 1 cps up to 100,000 cps with reduced speeds.
Gearchem pumps may be quickly inspected in the field. All that is required to inspect the
internal components is the removal of the rear housing. Before attempting an inspection or
repair be sure to read and thoroughly understand this maintenance manual.
Pumps may be repaired either in the field or at an authorized Eco Repair Center (contact
your Eco distributor for details). Field repairs can be done very quickly using an Eco KOPkit
which includes all the parts necessary to cover practically all routine maintenance
requirements.
2. EQUIPMENT INSPECTION
1. Check all equipment for completeness against the order and for any evidence of
shipping damage. Shortages or damage should be reported immediately to the
carrier and to your Eco distributor.
2. If the pump is not going to be installed immediately, the following steps should be
taken.
•
Leave pump in original shipping carton.
•
Store indoors in a dry ambient atmosphere. Avoid temperature variations.
•
Leave all shipping plugs in place.
•
Contact the motor manufacturer for specific motor storage information.
3. Occasionally during shipment, possible misalignment or other damage such as
cracked mechanical seal faces can occur. For this reason, it is recommended that
each unit be tested with water in some convenient area prior to piping into the actual
process system.
4. These instructions should be read carefully by the personnel responsible for
installation, operation and maintenance of the equipment and kept in a convenient
place for ready reference. It is recommended that a copy of the Eco order be kept
with this manual as well as a written record of the pump model number which is on
the name tag attached to the pump. A space has been provided inside the front cover
of the manual to record this number.
