6. Installation and mounting
6.1. Installing the DME Pump
Decide where the pump is to be installed and secure a site. The DME Pump installation place have to meet the
following requirements:
-
The suction lift should be kept as short as possible.
-
Sufficient space around the pump for maintenance must be provided. Free space required for the mounting and
disassembly of the pump and the unit
– at least 0.5 m up to 1.0 m (for all DME pump sizes) on all sides.
-
The pump can be operated without fastening to a foundation. However, in the event that a fastening is provided,
the fastening must be stress-free and must be made at the pump or engine support only. In that case use the
cushions on the pump base. The tied-down bolts should be tightened from time to time, to secure the pump.
TYPES OF INSTALLATION
SELF PRIMING APPLICATION
Suction lift capability may vary depending on the construction materials and
application parameters. The range is from 3 meters dry to 8 meters in a primed
condition (values calculated for pumping water at 20 degrees Celsius).
POSITIVE SUCTION HEAD
Common as a method of drawing off the bottoms of holding tanks and
clarifiers. Optimum inlet pressure should be kept at 0.2-0.3 bar.
