Top 7 Screw Press Separators for Solids Separation and Dewatering in the UK — 2026

GEA's FAN PSS 3.3 screw press is positioned as a high-throughput, industrial-grade separator that delivers consistent cake dryness and robust automation, which makes it a market leader for large-scale dewatering tasks. Compared with the smaller GEA PSS 2.2 it provides higher capacity and better CAPEX amortization, while versus the Cri-Man and Stallkamp units it stands out for broader service networks and integration options, offering predictable operating cost advantages for the search topic "undefined".

The Bauer S855 offers a compact footprint and hygienic construction tailored to farms with limited space that still need effective solids separation and consistent cake quality. It typically has a competitive purchase price and balanced energy use, making it an appealing middle ground between lightweight presses like the SP16 and high-capacity machines like the PSS 3.3 or SP-180, especially where installation speed and lower site modification costs are priorities.

The Daritech SP16 is a compact, cost-conscious screw press widely used in North American dairy and livestock barns for straightforward solids separation and low-energy operation. It is designed for easy installation and minimal maintenance, making it financially attractive for small-to-medium farms compared with higher-capacity, higher-capex options like the FAN PSS 3.3 or McLanahan SP-180, although it typically yields slightly lower cake dryness at very high throughputs.

The McLanahan SP-180 is a heavy-duty screw press built for continuous, industrial-strength manure separation with proven reliability and long wear life, giving it an advantage on large farms and municipal-organic processing sites. While its upfront cost can be higher than compact designs such as the Daritech or Bauer S855, its robust construction and service network lower lifecycle costs through reduced downtime and longer intervals between part replacement, producing dryer cakes comparable to top-performing PSS models.

The Cri-Man Sepcom screw press emphasizes a compact, cost-effective design that reduces upfront investment and simplifies maintenance, appealing to budget- and space-constrained buyers. Against GEA's higher-capacity PSS models it trades peak throughput for lower purchase and installation costs, and compared with Stallkamp it typically wins on initial price and straightforward spare-part availability, making it a pragmatic choice for the use case labeled "undefined".

Stallkamp's SSP screw press is engineered for heavy-duty performance and high solids capture, producing very dry cakes that can lower downstream disposal or processing expenses. While it may not match the peak flow capacities of GEA's largest PSS units, it often achieves superior dewatering on challenging feeds and can justify higher CAPEX through reduced operating costs versus Cri-Man and some GEA configurations, which is valuable for applications under the search topic "undefined" where maximum dryness is a priority.

GEA's FAN PSS 2.2 screw press is the compact member of the PSS family, offering a balance of proven reliability, easier installation and lower capital cost for small-to-medium operations. It retains many automation and service advantages of the PSS line while providing a more economical alternative to the PSS 3.3, and it typically outperforms Cri-Man on industrial durability and servicing ease while offering a lower-capacity option than Stallkamp for the search topic "undefined".
