PM20byB-e-s Single-Acting Manual Pump With Relief Valve

PM20byB-e-s is single-acting plunger manual hydraulic pump with built-in adjustable relief valve. Reciprocate the operating handle to drive inner plunger for linear reciprocating motion, changing pump cavity volume to realize hydraulic oil suction and high-pressure delivery, converting human mechanical force into hydraulic energy. The side-mounted relief valve realizes system overpressure unloading protection, effectively stabilizing output pressure.Core Advantages✅ Built-in Overload Safety Protection

Equipped with integrated relief valve, when system pressure exceeds preset value, automatic overflow limits peak pressure, preventing damage to pump body and matched hydraulic cylinders from overpressure, greatly improving equipment operation safety.

✅ Ergonomic Labor-saving Matching Design

Based on Pressure-Handle Force Diagram covering 0~600BAR working pressure range, customers can configure proper handle length against actual operating pressure referring to optimal intensity orange baseline, to keep hand operation within labor-saving range and reduce long-time work fatigue.

✅ Fixed Installation Ear Design

Pump body comes with reserved mounting lugs for quick fixation on hydraulic power unit, lifting frames and customized hydraulic equipment; compact layout saves installation space and simplifies pipeline arrangement.Application ScenariosSpecially matched with single-acting hydraulic cylinders, widely applied in automobile lifting equipment, mechanical maintenance hydraulic tools, small engineering auxiliary hydraulic systems and portable hydraulic power units requiring pressure limiting protection.
