GARDNER DENVER HORIZONTAL PUMP
RECOMMENDED SYSTEM LAYOUT FOR PROPER PERFORMANCE
NOTES:
1) Feed line and bypass line openings in tank
must be located below the top of baffle and
on opposite side of tank from outlet opening.
2) The baffle must be completely submerged at
minimum liquid level in the tank. The baffle
must be placed between the feed line and
tank outlet to pump and should extend from
one side of the tank to the other.
3) If a tank baffle cannot be installed, flow into
the tank must be directed away from tank
outlet to pump so entrained gasses do not
flow directly into tank outlet.
4) A short straight suction line is preferred from
the tank to the pump. If this is not possible,
use as few bends as possible and use long
radius elbows. The smallest portion of the line
should be at least as large as the pump
suction opening. Flow velocity should be 3
ft/sec or less.
5) Suction and discharge lines should each
contain a section of flexible hose to remove
piping strain and vibration.
6) The suction stabilizer should be a bladder
type with an internal baffle between the inlet
and outlet connections.
7) NPSH provided by suction system must be
adequate to satisfy pump requirements. Refer
to NPSHR curve or consult Gardner Denver
Marketing.
8)
A bladder type discharge pulsation dampener
is recommended.
9) Discharge line flow velocity should be 10
ft/sec or less.
