Summary – for Discharge Pressure Control

•The Clarke PLD for Discharge Pressure Limiting Control is a UL/FM certified diesel engine fire pump driver which reduces pump speed to limit the maximum pump discharge pressure to prevent over-pressurization of the sprinkler system. See Graph 1

•Certain Clarke PLD equipped engines (-P1 Models) are available with one of three different factory settings: 100 psi

• The Clarke PLD senses sprinkler system water pressure via a sensing line connected to the pump discharge pipe (between the pump flange and the discharge check valve), and adjusts engine speed to manage discharge pressure, see Graph 1. NOTE: -P1 models require a drainline, -D and –DS models do not.

• A Clarke PLD requires a controller equipped with visible and y g p(maximum pressure held between 100-110 psi), 170 psi (maximum pressure held between 170-175 psi) and 240 psi (maximum pressure held between 240-250 psi). Refer to Table 1 for Discharge Pressure Limiting Control values.

•Certain Clarke PLD equipped engines (-D and –DS Models) can be Factory Set at any specific pressure between 100 PSI and 350 psi. The value must be factory set and is not field

q q ppaudible alarms to comply with NFPA 20 Per 12.4.1.3 (8).

• When using a Clarke PLD for Discharge Pressure Liming Control, NFPA 20 requires the installation of a pressure relief valve.

• During commissioning, the PLD device is turned off in order to verify the performance of the pump to the factory test curve Therefore fittings and pipe with the appropriate higher

p yadjustable, refer to Table 1. curve. Therefore fittings and pipe with the appropriate higher

pressure rating need to be used from the pump discharge flange to and including the gate or butterfly discharge isolating valve.

NOISE DATA

Mechanical Engine Noise *

Installation specifics such as background noise level and amplification of noise levels from reflecting off of surrounding objects, will affect the overall noise levels observed. As a result of this, Clarke makes no guarantees to the above levels in an actual installation.

** Values above are provided at 23ft (7m), 90° horizontal, from a vertical exhaust outlet and does not include noise created mechanically by the engine.
