7. Maintenance
B EFORE 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 .
W EAR PROTECTIVE CLOTHING AND EQUIPMENT AS APPROPRIATE .
Accurate records from the 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 particular service conditions.
PULSAR KOPkits contain all replacement parts normally used in a preventative maintenance program. It
is recommended that KOPkits and PULSAlube hydraulic and gear oils be kept available at all times.
Each PULSAR 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 pump serial
number, pump specifications (i.e., materials, piston size, stroking rate, etc.).
7.1 Oil Changes
The recommended oil change intervals are dependent upon the operating environment and level of
pump usage, classified as follows:
1. Normal service: clean/dry atmosphere, an ambient operating temperature of 0
° C to 40° C (32° F to
104
° F) and up to 2,000 annual operating hours.
2. Severe Service: humid atmosphere, an ambient operating temperature below 0
° C (32° F) or above
40
° C (104° F), and over 2,000 annual operating hours.
7.1.1 Gear Oil Change:
The recommended gear oil change interval is five years for normal service and two years for severe
service.
Gear Oil change procedure is as follows:
1. Disconnect the power source to the drive motor.
2. Relieve all pressure from the piping system.
3. Remove the fill plug from the top of the gearbox.
4. Drain the oil by removing the drain plug on the bottom of the gearbox.
5. Replace the drain plug.
6. Refill with fresh PULSAlube 8G (amber) gear oil (refer to Gear Oil Fill, Section 5.1.2).
7. Replace the top fill plug and side plug (if removed).
