Pump’s Features

 

Full closed drive end：

1. The top of drive end with bearing and cover plate.
2. Higher concentricity, enhance output efficiency and drive efficiency.
3. Prevent the dirt into drive end, make the operation more stable and efficiency
4. Benefit to pump (without motor) delivery.

 

Casting and precision machining：

1. Precision casting, smooth surface and no sand hole.
2. CNC machining with high precision and concentricity.
3. EPOXY coating, strong and durable.
4. Structural reinforcement design, firm and durable.
5. The connecting bolts are made of stainless steel.

Eccentric drive mechanism：

1. Adopt forging process and precision machining, strong and durable.
2. Quenching and tempering treatment, wear-resistant and long life time.
3. Shaped structure coupling, fewer parts, high reliability and not easy to wear.
4. Precision machining, better concentricity and balance.

Worm gear and worm：

1. worm gear be bronze, wear-resistant and low noise.
2. Worm be alloy steel and tempered, high strength and wear resistance.
3. Adopt precision machining, good linearity and high gear meshing.
4. Two bearing support design, stable and high concentricity.

 

Double diaphragm chamber design：

1. Double diaphragm design, fluid chamber independent from the drive end.
2. Main diaphragm be multi-layer design, with high toughness PTFE surface.
3. Auxiliary diaphragm be Teflon, static sealing.
4. Once main diaphragm broken, Auxiliary diaphragm also can prevent the medium into drive end.

High strength diaphragm：

1. Multi-layer composite material.
2. The surface layer be high-toughness PTFE, support by an iron core, back layer be rubber reinforced with nylon fabric.
3. The whole diaphragm durable and stable.

High precision valve ball：

1. Ceramic or stainless steel.
2. Ceramic ball is made of yttrium stabilized zirconia material with high strength and wear resistance.
3. High roundness and good sealing performance.
