3. Equipment Inspection
Check all equipment for completeness against the order and for any evidence of shipping
damage. Shortages or damage must be reported immediately to the carrier and your
authorized representative or distributor of GLM
®
DM7 pumps.
4. Storage
4.1.1 Short Term
Storage of your GLM
®
DM7 pump for up to 12 months is considered short-term.
The recommended short-term storage procedures are:
a. Store the pump indoors at room temperature in a dry environment.
b. The lubricating oil should be added to the gearbox prior to storage
c. If required by the operating environment, take precautions to prevent entry of
water or humid air into the eccentric enclosure.
d. Prior to startup, perform a complete inspection and then start up in accordance
with instructions in this manual.
4.1.2 Long Term
Every twelve months, in addition to the above short-term procedures, power up the
motor and operate the pump for a minimum of one hour. It is not necessary to have
liquid in the reagent head during this operation, but the suction and discharge ports
must be open to atmosphere.
After twelve months of storage, Pulsafeeder’s warranty cannot cover items that are
subject to deterioration with age, such as seals, gaskets, and diaphragms. If the
pump has been in storage longer than 12 months it is recommended that these items
be inspected and replaced as necessary prior to startup. Lubricating oil should also
be changed prior to startup. Materials and labor to replace this class of item under
this circumstance are the purchaser’s responsibility. Consult your local Pulsafeeder
representative for assistance in obtaining parts and service for your pump.
5. Installation
5.1 Location
When selecting an installation site or designing a chemical feed system,
consideration should be given to access for routine maintenance.
GLM®DM7 pumps are designed to operate indoors and outdoors, but it is desirable to
provide a hood or covering for outdoor service. External heating is required if ambient
temperatures below 0° C (32° F) are anticipated, especially if pumps are not in
continuous duty. Check with the factory if concerned with the suitability of the operating
environment.
The pump must be rigidly bolted to a solid and flat foundation to minimize vibration,
which can loosen connections. When the pump is bolted down, care must be taken to
avoid distorting the base and affecting alignments. The pump must be level within 5°.
This will assure that the check valves can operate properly.
