A hand-operated hydraulic pump is a manual device that uses mechanical effort to pressurize hydraulic fluid (usually oil), which is then used to power hydraulic cylinders, tools, or systems. How It Works: 1. You pull or push the handle, which moves a piston inside the cylinder. 2. This movement draws fluid from the reservoir and then forces it out under pressure. 3. The fluid travels through hoses to power hydraulic equipment like a jack, cutter, or expander. hand operated hydraulic pump manufacturing in mumbai airoli maharashtra hand operated hydraulic pump manufacturing in mumbai airoli mumbai hand operated hydraulic pump manufacturing in mumbai airoli navi hand operated hydraulic pump manufacturing in mumbai airoli navi mumbai hand operated hydraulic pump manufacturing in mumbai airoli sector
