Cs Hand Piston Pump

Robust, manually operated piston pump designed for marine and industrial fluid transfer where electricity is unavailable or undesirable. The CS series hand piston pump is suitable for pumping lubricating oil, fuel oil, other light lubricants, fresh water and seawater (no hard particles or fibers). Typical applications include shipboard service, civil air‑defense engineering, firefighting, well water drawing, kitchen sewage oil/water handling and vehicle transport departments.

Key features:

• Manual piston (hand) operation with excellent self‑priming performance for reliable suction from tanks and sumps
• Compact and lightweight construction for easy installation and portability
• Corrosion‑resistant design and materials treatment on critical parts for extended life in marine environments
• Simple construction for straightforward maintenance and repair
• Suitable for liquids with temperatures up to 60°C

Materials and main components:

• Pump body, cover, piston: ZL102 (aluminum alloy)
• Cylinder (oil pump): HT20‑40 (cast iron grade)
• Cylinder (sea water pump): H62 (brass)
• Valves and shaft/connecting rod: 2Cr13 (stainless steel)
• Valve seat: H62 (brass)

Model coding (example CS-20Y(H)):

• C = Marine pump
• S = Hand pump
• 20 = Inlet/outlet bore 20 mm
• Y = Oil pump variant
• H = Sea water pump variant

Benefits for B2B buyers:

• Low lifecycle cost due to simple, serviceable design
• Versatile: one pump family covers oil, fresh water and seawater duties by selecting appropriate cylinder material
• Easy to deploy on small vessels, remote sites or emergency applications where powered pumping is impractical

If you require specific performance data (flow rate, suction lift, dimensions, mounting options) or material certificates for compliance, request the technical datasheet or site application details so the correct CS model variant can be recommended.
