Manual high flow diaphragm pump

The manual high flow diaphragm pump is a human driven large capacity conveying equipment that relies on manual reciprocating operation to drive the diaphragm reciprocating motion to achieve fluid conveying. It does not require electricity or fuel, and the power is purely driven by human labor. It has a large flow rate, strong suction, and stable conveying. It is widely used in construction sites, oil depots, chemical plants, farmland irrigation, sewage transfer, field emergency transportation and other scenarios. It is the preferred tool for high flow non electric conveying operations.

The overall structure of the machine is firm and compact, and the pump body is made of thickened and excellent materials, which are resistant to compression and wear (based on actual reports), corrosion and aging, and overall seismic and drop resistance. It can adapt to various complex and harsh environments such as oil stains, humidity, and outdoor conditions, and is not easily damaged or deformed after long-term use.

. The core adopts a double diaphragm boosting structure design, which ensures smooth power transmission and strong suction force. Compared with ordinary manual pumps, it has a larger flow rate, longer conveying distance, excellent high and low drop conveying capacity, and greatly improves operational efficiency.

The equipment is easy and labor-saving to operate, with a reciprocating pressure rod design that conforms to ergonomics. The pushing, pulling, and pressing feel are smooth, and the force is easy to apply. Long term operation is not easy to fatigue, and both men and women can operate normally.

. By relying on the elastic deformation of the diaphragm to form negative pressure suction and positive pressure discharge, the inlet and outlet velocities are suitable for smooth flow. The large-diameter flow design reduces fluid resistance, resulting in a large output volume with uniform and stable flow velocity, without pulsation or interruption, meeting the needs of large-scale speed suitable pumping.

Built in detailed one-way inlet and outlet valve group, tightly sealed without leakage, with excellent effect to prevent liquid backflow. Stop the pump to lock the medium, avoiding material waste and pipeline backflow problems.

. The sealing components have stable oil resistance and are suitable for transporting various media. There is no leakage throughout the operation, and the working environment is clean and tidy.

There is a wide range of suitable conveying media, which can easily extract diesel, engine oil, various industrial oil products, as well as transport various non large particle impurity fluids such as clean water, sewage, waste liquid, chemical thinner, agricultural liquid, etc. It has strong versatility.

. The device comes with good self-priming ability, without the need for pre infusion or water intake. It can be placed in place to start pumping at a suitable speed, making it more convenient to use.

Pure mechanical manual structure, no motor circuit, safe explosion-proof (based on actual reports), no electrical hazards, can be safely used in flammable and explosive places, remote areas without electricity, and is not limited by site power supply.

. Easy to install and use, simply connect to a universal hose to put it into use, with flexible fixation and movement, and easy disassembly and transportation.

Daily maintenance is simple and worry free. After use, the residual liquid in the pump can be emptied, and impurities in the inlet and outlet filter screens can be cleaned. The internal structure is simple and the failure rate is relatively low. The replacement of vulnerable parts is convenient, and the maintenance cost in the later stage is low.

With outstanding advantages such as high flow conveying, strong suction, good practicality, no need for electricity, and safe practicality, it can not only meet the suitable speed of barrel liquid transportation, but also complete short distance tank liquid transfer and emergency pumping in the field. Its practicality far exceeds that of conventional small manual pumps, making it a necessary equipment for high flow manual conveying in the industrial, agricultural, and maintenance industries.
