Maximum Efficiency: The best efficiency point is where the efficiency of the pump is at its maximum. When operating at this point, the pump will convert electrical energy into fluid energy with maximum efficiency and minimal energy loss.

Process pumps play a vital role in many fields, including but not limited to:

This product is with compact structure, stable flow rate without pulsation, reliable operation, available for high speed, low noise, small vibration, high efficiency, long -service life, strong self-priming ability and so on, and can be widely applied in metallurgy, petroleum, chemical , power, transportation, building materials, marine, etc.

Application scope of single screw pump:

1. Petrochemical industry: the delivery oil, acid, alkali and salt solution, various viscous pasty and milky chemical grout, oil water separation and waste oil recycling system, polymer delivery.
2. Environment protection: industrial and life sewage treatment, oily water treatment, the delivery of various muddy water with solid particles and short fiber, oil water separation and waste gas project, measuring addition of flocculant and its chemical agents.

Application  scope of three screw pump

1. Medium: lubricant (oil), vegetable oil, water ethylene glycol (priority)

lubricating grease, light diesel oil, fuel wastage(oil), there sticky chemical medium (being allowed)

2. Requirements of performance

• Lubricating requirements is required.
• No solid particles.
• Flow range: 5-5300L/min
• Required speed:500-3000r/min
• Service temperature: 0-150℃
• Operation pressure: not more than 4.0 MPA
• Viscosity range:3-1500m²/s
• Allowed suction head: not more than 8meter

For the transportation of high-viscosity materials (heavy oil, asphalt, etc.), screw pumps (heating pumps) are more advantageous.

The one-time investment of the progressive cavity pump is higher and the gear pump is relatively economical, but the one-time investment of the pump, the maintenance cost, the electricity cost and the elimination cost are the same under the same conditions.

Type G or GH gravel pumps are designed for continuously handling the most difficult abrasive slurries which contain too big solids to be pumped by a common pump. They are suitable for delivering slurries in mining , explosive -sludge in metal metaling . Dredging in dredger and course of rivers, and other fields. Type GH pumps are of high-head ones.

We can supply with various warman slurry pump wear parts including in MCR150, MCR350,MCR400,MCR450,MCR550 at comperitiv price.

The slurry pump is composed of flow parts, sealing structure, pump body，pump cover, bearing assembly and bracket frame. The sealing structure is divided into gland seal and expeller seal, and the flow parts are divided into metal flow parts and rubber flow parts. The flow parts of the slurry pump are mainly composed of three parts: impeller, sheath and guard plate, and their roles and classifications are introduced in the following decibels
