4. Installation
4.1 Location
When selecting an installation site or designing a skid package, consideration should be given to
access for routine maintenance.
PULSAR Shadow
® 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
O C (32 O F) are anticipated. 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
O . This will assure that the
eccentric and gear oils are maintained at the proper levels and that the check valves can operate
properly.
4.2 Piping System
All piping systems should include:
1. A separate system relief valve to
protect piping and process
equipment, including the pump,
from excess process pressures.
*An external relief valve is
required, as a mechanical
diaphragm pump does not
incorporate an internal relief.
2. Shutoff valves and unions (or
flanges) on suction and discharge
piping. This permits check valve
inspection without draining long
runs of piping. Shutoff valves
should be of the same size as
connecting pipe. Ball valves are
preferred since they offer
minimum flow restriction.
