Hand Pump for the Single-Arm Boat Davit of the Rescue Boat
No.PM70
Hand pump is a device that converts mechanical energy into liquid pressure energy. It generates power through manual operation and then drives the piston or piston inside the pump to perform reciprocating motion, causing the sealed volume to periodically increase and decrease, thereby completing the process of oil suction and oil discharge. This type of pump is usually widely used in situations requiring liquid transportation or pressure enhancement, such as in ships, metallurgy, power, and heavy machinery fields.
Manual Fluid Control for Rescue and Marine Use The JESI marine hand pump offers precise manual pressure control in critical marine operations. Designed for single-arm davit systems on rescue boats, it transforms manual mechanical input into fluid movement through a piston-driven mechanism. Built to withstand harsh maritime environments, it enables operators to perform davit system activation and fluid transfer tasks without electrical power, ensuring reliable function in emergencies.
Built for Cooling and Auxiliary Transfer Systems In addition to its primary function on rescue boats, this marine pump serves as a dependable manual alternative in cooling water pump circuits. Whether circulating coolant fluids in engine systems or moving lubricants between tanks, it ensures consistent operation under manual control. Its simplicity and tool-free operation reduce system downtime and enhance onboard readiness.
Adaptable Beyond Maritime Environments With its robust, corrosion-resistant build, the JESI pump is not limited to shipboard use. It finds utility in rural or off-grid operations, where it functions as an effective agricultural pump. For field operators requiring portable, non-electric fluid handling, this pump provides reliability and durability wherever pressurized fluid movement is needed.
Product Advantages
No-Power Operation with High Reliability The pump operates entirely manually, providing pressure and fluid transfer capability without any external energy source. It is ideal as a backup or standalone unit for boat hand pump needs in davit deployment or auxiliary tasks.
Corrosion-Resistant Marine Construction Made with durable and saltwater-resistant materials, the JESI hand pump is built for harsh marine conditions. It requires minimal maintenance and maintains performance over long-term use, even in environments with oil, coolant, or salt exposure.
Compact Design for Versatile Mounting This marine hand pump features a small footprint and simplified installation, making it easy to integrate into tight onboard spaces. It also allows for flexible positioning in agricultural and service applications where portability and ruggedness are key. Usage Scenarios
Emergency Rescue Boat Deployment The pump’s primary use is in manual activation of single-arm davit systems, allowing for reliable launch and retrieval of lifeboats during power outages or emergency drills.
Cooling System Backup in Marine Engines Onboard ships, this pump serves as a standby cooling water pump to manually circulate coolant in engine compartments or auxiliary cooling systems when automatic pumps are offline.
Off-Grid Agricultural Water Transfer In farms or field environments without electricity, this pump functions as a portable agricultural pump to transfer irrigation water or fertilizers, helping maintain productivity in isolated areas. About Us
