Maintenance
Accurate records from early stages of pump operation will indicate the type and levels of required
maintenance. A preventative maintenance program based on such records will minimize operational
problems. It is not possible to forecast the lives of wetted parts such as diaphragms and check valves.
Since corrosion rates and operational conditions affect functional material life, each metering pump
must be considered according to its service conditions.
Each PulsaPro pump is provided with an individual specification data sheet included in the parts list
package. The data sheet contains important information relating to the application along with the pump
serial number and pump specifications (i.e., materials, piston size, stroking rate, etc.).
PulsaPro KOPkits (
K
eep-
O
n-

umping) contains all the replacement parts normally used in preventative
maintenance program. It is always recommended that KOPkits and PULSAlube hydraulic oil be kept
available. A good instruction manual, parts list, and a good maintenance record are key to long trouble-
free metering pump operation.
BEFORE PERFORMING ANY MAINTENANCE REQUIRING REAGENT HEAD OR VALVE (WET
END) DISASSEMBLY, BE SURE TO RELIEVE PRESSURE FROM THE PIPING SYSTEM AND,
WHERE HAZARDOUS PROCESS MATERIALS ARE INVOLVED, RENDER THE PUMP SAFE TO
PERSONNEL AND THE ENVIRONMENT BY CLEANING AND CHEMICALLY NEUTRALIZING AS
APPROPRIATE. FOLLOW SAFETY MEASURES BY WEARING YOUR PROTECTIVE CLOTHING
BASED ON THE HAZARDOUS.
8.1 Operating Precautions
All operations must be performed by qualified personnel. Prior to work:
o
The power line is disconnected, and no parts are energized
o
Any risk of accidental restart has been excluded
o
Handled fluid, present in the pump head and pipelines is not pressurized
o
With the pump off, suction and discharge valves are closed
o
Pump has been adequately cleaned, when operating in aggressive chemical environments
THESE MAINTENANCE SUGGESTIONS ARE NOT INTENDED AS “DO IT YOURSELF” REPAIRS.
TO PERFORM SUCH WORK, SPECIALIZED TECHNICAL KNOWLEDGE IS REQUIRED, AND
OPERATIONS ARE TO BE PERFORMED BY QUALIFIED PERSONNEL.
8.2 Consulting with Technical Documentation
Before starting work, you should consult this maintenance manual, identify the correct sectional drawing
of the pump in use and get all the tools and equipment necessary to perform the maintenance or repair
work.
When the pump has been disassembled, waiting to be reassembled, it is necessary to protect the
various components to prevent damage caused by oxidation or accidental impact.
8.3 Oil Changes
It is recommended after six months of operation to replace the hydraulic oil within the PulsaPro pump.
To accomplish this, you will need to remove the drain on the gearbox as well as the drain plug on the
intermediate head. Oil changes thereafter would be on an annual basis for Normal Service, or every six
months for Severe Service as defined below.
Normal Service:
Clean/Dry Atmosphere, an ambient operating temperature of 0°C to 40°C (32°F to
104°F) and/or up to 2,000 annual operating hours.
