Crest Pumps - Model CSS Range -Cantilever Corrosion Resistant Sump Pump

Built with a cantilever shaft design, CSS pumps have no immersed bearings which allows the pump to run-dry indefinitely without damage. Bearings aren’t required at the bottom of the pump due to the oversized shaft which adds stability to prevent shaft whipping.

• Capacity: <65m³/hr
• Head: <40 metres
• Column Length: <750mm
• Minimal Maintenance
• Total Corrosion Resistance
• Run Dry Capability

The vertical range are proven to stand the test of time offering solid performance constantly throughout the pumps lifetime. And because of their run dry capability, minimise both operational costs and maintenance costs whilst keeping your process running efficiently and reliably. To ensure that we supply you with a pump that will last in the harshest of environments, pumps are available in a variety of materials including polypropylene, PVC, PVDF and 316 stainless steel. Every plastic vertical pump in our range is designed and manufactured in the UK so we can tailor the pump to your exact requirements – whether that be a particular column length, mounting plate shape or outlet position. Usually with very little difference in price or lead time compared to a standard pump.

The CSS range of vertical plastic pumps have been perfected over 40 years to combat harsh and corrosive chemicals making the CSS range ideal for applications such as sump emptying, recirculation, effluent treatment and fume scrubbers. Built with a cantilever shaft design, CSS pumps have no immersed bearings which allows the pump to run-dry indefinitely without damage. Bearings aren’t required at the bottom of the pump due to the oversized shaft which adds stability to prevent shaft whipping. The CSS range is available in polypropylene, PVC, PVDF or 316 stainless steel for the ultimate corrosion resistance to harsh and acidic applications. O-rings are available in Viton, EPDM or Kalrez. The support column is fabricated and incorporates a double skinned, heavy duty tube arrangement making the CSS range of pumps exceptionally rugged and robust.

Upfront prices are just the beginning — energy and maintenance make up most of a pump’s lifetime cost. Our Lifecycle Cost Calculator (LCC) breaks it down, helping you compare different pump types and manufacturers to find the best solution for your needs.
