The BERMAD FP-60F-D/DV Basket Strainers are
intended to be installed in fire protection pipelines
primarily to prevent the clogging of fire sprinkler
nozzles and other debris sensitve components in
water or foam fire systems.
The BERMAD FP-60F-D/DV is designed for in-line
maintenance available with a large diameter flushing
outlet for easy screen cleaning and simple screen
basket extraction, requiring only cover removal.
The ratio of the FP-60F-D/DV strainer’s basket screen
area to the inlet pipe area is more than 10:1, ensuring
continued system performance, a low pressure drop
and longer intervals between cleaning.
NFPA 11, 13, 15 and 16 standards state that listed strainers
shall be provided in the main pipeline of all systems
using nozzles where the water is likely to contain
obstructive material.

Design Engineer Guide
The BERMAD FP-60F-D/DV Basket strainers are for use in firewater supply and are capable of preventing the entrance
of solids that might block or clog fire protection nozzles or other sensitve devices.
Install the FP-60F-D/DV strainer upstream of the sprinkler valve, deluge valve, pressure control valve or any other
debris sensitive system device.
The Strainer must be located where there is adequate clearance for removal of the basket screen assembly to enable
easy extraction and inspection of the strainer basket.
Install the strainer such that there will be adequate drainage for the release of water when opening the strainer for
service and for the dirty water exhausted during the cleaning of the strainer screen using the flushing valve.
The flushing drain connection should be typically fitted with an appropriately sized normally closed valve and drain piping.
Where a flushing valve is to be employed, the FP-60F-D/DV Basket Strainer sizes 3" to 12" are recommended to be installed
in a horizontal position with the strainer cover and flushing valve to the side. To facilitate flushing for 14" and 16" sizes
installation is recommended to be vertical.
The strainers shall be installed and maintained in compliance with the NFPA-25 standard in the addition to the instructions
given by the authorities having jurisdiction.
The NFPA-11 standard requires that a listed strainer with a screen area to pipe cross section area ratio of 10:1 shall be used with
foam proportioners or foam generators, and should be installed in the water pipeline upstream of the water control valve.
The NFPA 13, 15 and 16 standards stipulate that a Listed Strainer shall be provided in the main pipeline of all systems
utilizing nozzles with waterways less than
3
⁄ 8 " (9.5 mm) and for any system where the water is likely to contain obstructive
material. Strainers shall be capable of removing from the water all solids of sufficient size to obstruct the nozzles.
Engineer Specifications
The Fire Line Strainer shall be a basket type strainer UL listed.
The strainer shall be with high flow capacity and low pressure loss.
The strainer shall include a flushing valve capable of quickly and efficiently cleaning the strainer screen without removing
the strainer cover, or closing system pressure.
The strainer body and cover shall be ductile iron ASTM A536 65-45-12 with anti-corrosion Fusion Bonded High Build
Epoxy RAL 3002 coating internally and externally, all other wetted parts shall be stainless steel 316.
The screen shall be inline removable basket type, made of stainless steel 316 with screen holes diameter of 3.2 mm
(1/8"), meeting the requirements of the NFPA codes and standards. The Strainer basket screen area shall be at least 10:1
compared to the cross-sectional area of the pipeline.
Strainer maintenance, inspection or service shall be carried out in-line and without disassembly of the strainer body
from the pipeline. The Strainer shall be supplied pre-assembled with stainless steel bolting and hydraulically tested by
a factory certified by the ISO-9001 standard.

Installation
Provide basket removal clearances and strainer installation provisions in accordance with the requirements given in
the Design Engineer Guide section above. Install the strainer with the flow arrow on the body pointing in the desired
flow direction.
The strainer should be installed such that the flushing valve Drain Flange is at the lowest point of the strainer, 3" to
12" strainers have the flushing valve port on the cover that can be rotated to be at the lowest point, this is to facilitate
efficient cleaning of the screen while flushing.
The strainer shall be installed on the pipeline upstream of the sprinklers, pressure control valve, deluge valve or any
other sensitive system device. Install a listed isolating valve upstream of the strainer. An adequate support shall be
provided to carry the system installation as well as the dynamic loads.
It is recommended to install a differential pressure gauge rooted to upstream and downstream of the FP-60F-D/DV
strainer, in order to show the degree of strainer blockage. The maximum allowable differential pressure across the
strainer is 7 psi or 0.5 bar at maximum system flow.
Placing In Service
Verify that all strainer cover bolts are well tightened, close the drain plug and/or drain valve, slowly open the supply-
isolating valve and check that there are no leakages. Observe the system pressure gauge: it should indicate that the
normal supply of water pressure is maintained.
Typical Installations
The BERMAD FP-60F-D/DV strainer is ideal to be installed
upstream of the BERMAD Pressure Control Valve, preventing
the fouling of valve sealing surfaces and keeping the
waterways clear from obstructions.
The BERMAD FP-60F-D/DV strainer should be installed
upstream of the Deluge, Foam system or Automatic Sprinkler
system, preventing debris particles from clogging the
nozzles and other sensitve devices.

Maintenance
The following inspection procedure must be performed as indicated, in addition to specific requirements of any applicable
standards. Any damage or performance deficiency must be immediately corrected.
The fire system shall be inspected, tested, and maintained by qualified service personnel in accordance with local
requirements and/or national codes.
Preventive Maintenance
The frequency of inspection is dependant on the quality of the firewater, even so it is recommended that the strainer's
basket screen be removed and cleaned at least annually in addition to flushing after each operation or system flow test.
For the model FP-60F-DV that includes a flushing drainvalve, strainer cover removal for cleaning may be avoided
when a differential pressure gauge / transmitter across the strainer is provided. This device will indicate if the pressure
differential is satisfactorily below the maximum allowable 7 psi (0.5 bar) across the strainer screen at the maximum
system flow rate. If so, this shows that the screen is not dangerously blocked and a flush cleaning with the drain valve
should prove sufficient. However it is recommended to remove the strainer cover at least annually for inspection.
Inspection and Cleaning
Verify that the strainer is depressurized and drained before the disassembly of any strainer component.
The strainer basket screen should be cleaned after each system operation or flow test and during routine inspections,
as follows:
For strainers fitted with a flushing valve:
1. Fully open the flushing drain valve for at least 5 seconds or until the flushed water becomes visibly clear.
2. Close the flushing valve tight.
For periodic inspection and cleaning of screens for strainers without a flushing valve:
1. The system must be shut down and completely drained.
2. Remove the strainer cover and the basket screen.
3. Clean out the basket screen, as well as the interior of the strainer body.
4. Reinstall the basket screen, make sure that the basket is fully inserted into the strainer body and is correctly orientated.
5. Inspect the gasket O-ring and replace if needed.
6. Reinstall the strainer cover, gradually cross tighten diametrically and sequentially all bolts so as to apply uniform load
for the cover seal.
