Description of KVP SEA CHEST FILTER

KVP produces filters for the most important naval companies.
The KVP sea chest FILTER is composed by two components:
- a GRP BODY
- an INTERNAL FILTER in AISI 316

The GRP BODY
Is a cylindrical Glass Reinforced Plastic top flanged body with an elliptical (or flat inclined) bottom. An elliptical (or flat) flanged cover is connected to the flange of the body in order to be dismantled and lifted when necessary. Two flanged connection on the cylinder provided at sea water inlet and outlet after filtration. On the bottom, the filter has three support legs and one flanged drain, on the top of the cover there is a flanged vent.

The INTERNAL FILTER
Is made of AISI 316 steel and can be removed when necessary.
This AISI steel cylindrical part is made with a various diameters holed plate where diameter of holes depending from the service, the holes are placed at various fixed position and slope arrangement.
This filter had developed for more than half of the circumference.
The remaining part of the wall is open to allow water to enter.
The roof is composed by a structural ring reinforce and a plate, which two parts are made by the same hole plate of the body in order to realize the filtration through these parts too.
The structural reinforced plate on the bottom has a few number of holes, acting as a drain during lifting operation. 4 anodes are positioned on the roof and bottom to prevent corrosion.
Filter have also 4 spacers covered by Teflon, to preserve the internal part of the chest during the movements of the filter.
This arrangement permits a safety movement of the filter during the lifting operations for cleaning and during the filter filling operations.
Flanges are fixed flanges type drilled according to the ISO EN1092 PN 10/PN16.

Thickness of the structure depends from the working pressure.

KVP filters are characterized by high “Beta Ratio” and high “Efficiency” compared to similar in the same category.
