Barnes
Cast iron, oil-filled submersible solids-handling pumps for municipal sewage, wastewater, and effluent duty — the Solids Handling (SH) Series, 18 and 21 Frame, 2-30 HP.
What LibertyCES specifies from Barnes
Barnes is a brand of Crane Pumps & Systems (Crane Co.), founded in Piqua, OH in 1946 and acquired into the Crane Pumps & Systems division in 1993. It is best known for oil-filled, cast iron submersible pump construction built for demanding wet-well solids-handling duty. LibertyCES reaches Barnes through E-Water Solutions, LLC — its existing Southern California pump distribution partner, which names Crane Pumps & Systems/Barnes directly on its own line card.
Cast iron oil-filled submersible construction, 2-10 HP, 3in/4in discharge, 1750/3450 RPM — the lower-HP entry point into the SH family.
Cast iron oil-filled submersible construction, 7.5-30 HP, 4in/6in discharge, 1150/1750/3450 RPM — reaches higher-head, higher-HP duty points than the 18 Frame.

Sourced from Barnes/Crane Pumps & Systems installation manuals (depcopump.com/datasheets/barnes/4SHV.pdf, 6SHV.pdf). Overall-series marketing claims (motors to 150 HP, larger 8SH/10SH/6XSH/8XSH/10XSH models) exist on distributor pages but have not been independently confirmed at the installation-manual level — LibertyCES lists only the 18/21 Frame data it has verified.
Frequently Asked Questions
What's the duty range for Barnes SH Series pumps?
The confirmed 18 Frame and 21 Frame installation-manual data covers 2-30 HP, 3in-6in discharge, and 1150/1750/3450 RPM. Crane Pumps & Systems' own overall-series marketing claims flows to 6,400 GPM, heads to 305 ft, and motors up to 150 HP across the full SH lineup (8SH, 10SH, and larger frames) — but LibertyCES has not independently pulled installation-manual specs above the 30 HP / 21 Frame range yet. Send James your duty point and he'll confirm the right frame with E-Water Solutions before quoting.
Is Barnes or Cornell Pump the better fit for high-head municipal sewage duty?
Both are viable, and the right pick depends on the specific duty point. Barnes SH Series is a purpose-built submersible solids-handling line with a confirmed 2-30 HP range on file; Cornell Pump's published submersible/solids-handling range goes further on paper (up to 20,000 GPM, 450 ft head) but LibertyCES only has one specific Cornell model (4NHTB) partially read off a performance curve, not yet a certified sheet. For a confirmed spec at this stage, Barnes SH is the safer starting point — ask James for a duty-point comparison against both.
Why do different sources list different overall-series numbers for Barnes SH pumps?
Crane Engineering's own product page lists flows to 6,400 GPM and heads to 305 ft; a different reseller (Overseas Motors) lists the same family at flows to 4,000 GPM and heads to 265 ft. This is a real, unresolved discrepancy between distributor marketing pages — LibertyCES cites the confirmed 18/21 Frame numbers from real installation manuals rather than picking one of the conflicting overall-series figures.
