PSV Series FRP Pump Station With Valve Pit

One of the most crucial benefits of a valve pit is increased safety. Servicing a pump station ordinarily involves some risk as one has to reach inside the pit to turn off the valves. A valve pit eliminates the need to reach into an open pit.

• Single, dual or triple pump setups.
• Free standing or guiderail pump setups.
• PVC, PE, cast iron pipe work systems.
• Brass, cast iron, bronze or stainless steel valving.
• FRP pipework supports.
• Float or probe hooks.
• All auxiliary connections (penetrations) as per customer specifications.
• Galvanised or stainless chain setups.
• Aluminium, cast iron or fibreglass access covers.
• FRP inlet stilling tubes.
• Knife gate valves on inlet with risers and valve stop box.
• Inlet grinder guide rails.
• Duck bill check valve on valve pit drain.

WSA Product Appraisal

Our Pump Stations have been appraised by Water Services Association of Australia.

Advantages

Engineered

All stations have been individually engineered to handle the toughest environmental situations.

Proven in the toughest environments including installations in volcanic soils and high water tables.

Reduce OH&S Risks and Cost

Minimum ground opening time reduces labour costs and reduces OH&S issues on site.

Light Weight

• The relatively light weight simplifies handling and reduces costs in transport, handling and installation.
• No heavy cranes and assembly of heavy concrete sections in the ground; saving considerable costs.
• Even though the FRP Pump stations are relatively light weight, pound for pound  they are stronger then their competitors materials.
• Due to the relatively light weight, ease of onsite installation and access again reduces labour cost and down time is reduced.

Corrosion

• The problem of corrosion due to sewer gases in concrete wells is entirely eliminated giving long life with minimum maintenance. The pump wells are manufactured in high grade chemical resistant isophthalic resins and are built to Australian and British Standards.
• Sewer gases in concrete wells is eliminated by using the FRP Pump stations which are corrosion resistant.
• Prevention of concrete cancer (spalling).

Cleanliness

The stations have no joins. Being built in one piece, they have a seamless, smooth, clean internal surface that resists scum and sludge build up and allows no leakage to the external environment.

The design, construction and appropriateness of design methodology of all FRP structures is verified and within the bounds of AS2634:1983, BS4994 and ASME RTP-1 (for details of the verification process please refer to Verification Procedure). The general construction of the station is as follows:

• Internal Corrosion Barrier Contact Moulded
  0.5mm “C” Glass Veil Surface layer with Hetron 922 (or equivalent) Vinyl Ester Resin
• Internal Corrosion Barrier Backing Layers
  2.5mm ‘E’ Glass Chop Strand tie layer with Hetron 922 (or equivalent) Vinyl Ester Resin
• Structural Laminate
  ‘E’ Glass reinforcement in chopped and continuous strands. Minimum glass content 50% (Thickness according to Design requirements)
• Structural Stiffeners
  Polyurethane Foam rib former overlaid with ‘E’ Glass reinforcement in chopped and continuous strands. Minimum glass content 50% ( Size and Thickness according to Design requirements)
• External Surface – Final Surface
  0.5mm “C” Glass Veil Surface layer with Hetron 922 (or equivalent) Vinyl Ester Resin
• External Surface – Sealer
  Pigmented ISO/NPG Flowcoat for external protection

Minimum Standards of Design and Construction shall be

• BS4994 – 1987 Design & Construction of vessels & tanks in reinforced plastics
• AS2634 – 1983 Chemical Plant equipment in GRP
• AS1546 – 1983 Underground Tank design
• AS1770 – 1981 Loading Code

Material Properties

All material mechanical properties are in accordance with international standard BS4994 and are suitable for the intended design and anticipated service conditions.

All structures are Designed, Engineered and Verified as per our procedure set out in our Pump Stations Brochure.

Transport

Due to the high strength-to-weight ratio of an FRP pump station, the process of loading, transport and unloading is simple.

There are no weight issues with FRP as there are with pump stations manufactured out of other materials. Special equipment such as low loaders and overweight floats are unnecessary. Only standard transport/ lifting equipment is required.
