GENERAL DESCRIPTION
PEP HMF2 Series Industrial Water Filters are permanent media type units specifically
designed to remove suspended particulates from industrial and process water. HMF2
filters are suitable for both side-stream and in-line applications on pressurized systems.
The standard pressure rating for HMF2 filter systems is 100 psig (700kPa). Optional
higher pressure ratings and ASME coded vessels are available.
Filter Operation
Unfiltered system water is pumped through the HMF2 filter inlet and over-drain
assembly at the top of the filter tank where it is distributed evenly over the media.
Suspended particles are entrapped within the filter media. The resulting filtered water
then passes from the vessel through the under-drain assembly at the bottom of the
filter and is returned to the system.
When trapped particles cause the pressure differential across the media bed to reach a
pre-determined pressure of approximately 16 psig, the valves are automatically or
manually repositioned and the media is backwashed with a rigorous scouring action for
approximately two minutes. The accumulated particulate exits the filter vessel via the
over drain assembly and flows to drain. After which, the valves are returned and
filtration continues.
Installation
Unpacking
Immediately upon receipt, the PEP HMF2 filter should be checked thoroughly to
ensure that all required items have been received and the filter equipment is free of
any shipping damage prior to signing the bill of lading.
The filter model number appears on a nameplate located on the unit and should be
checked against the invoice/packing list.
Rigging
1. The PEP HMF2 units should be lifted with a forklift or overhead crane. If
these units are lifted with an overhead crane, lifting straps must be located
below the filter skid and should not come in contact with filter components.
For non-skidded filters, use lifting lugs located at the top of the filter vessel.
2. All PEP water filters should be rigidly anchored to the floor or support steel by
means of anchor bolts. The HMF2 has holes suitable for 3/4" anchor bolts.
