Hebei High Pressure Industrial Water Centrifual High Head Slurry Pump
LongTeng HH series were designed to produce high heads per stage at high pressures. commonly used for long distance transport lines, the HH lines can often satisfy application duties with a single pump where others require multiple pumps.the range is capable of handling medium size particles and pumping at heads in excess of 90 meters per stage.
This series pumps are available in three seal forms:
(1) Auxiliary impeller power seal: the auxiliary impeller seal uses the pressure seal generated by the impeller and the auxiliary impeller in series, and the packing or lip seal ring as the parking seal
seal up. When the positive pressure at the pump inlet is not greater than 10% of the pump outlet pressure, the single-stage pump or multi-stage series pump adopts this sealing form.
(2) Packing seal is a common form of shaft seal, which is suitable for various working conditions and can match with special packing such as tetrafluoroethylene packing and graphite packing
Material, which can be used under abrasive or high temperature conditions. It has the advantages of simple structure and convenient maintenance.
(3) Mechanical seal: advanced sealing technology is adopted, with good sealing effect. The container structure makes the installation and replacement more convenient, and different structural shapes
It can adapt to different working conditions. The friction pair is made of high hardness ceramic or alloy materials, and the design and coordination of mechanical seal and sealing box comply with the medium flow
Dynamic state, so it has high wear resistance and earthquake resistance, and can satisfy customers under various working conditions.
Design Features:
1. Bearing assembly - a large diameter shaft with short overhang minimizes deflection and contributes to long bearing life. Only four through bolts are required to hold the cartridge type housing in the frame.
2. Volute Liners - easily replaceable liners are bolted, not glued, to the casing for positive attachment and east of maintenance. Hard metal liners are completely interchangeable with pressure moulded elastomer.
3. Elastomer seal rings back all liner joints.
4.Pump casing - Casing halves of cast or ductile iron with external reinforcing ribs provide high operating pressure capabilities and an extra measure of safety.
5. Impeller-front and rear shrouds have pump out vanes that reduce recirculation and seal contamination. Hard metal and moulded elastomer impellers are completely interchangeable.
6. Cast in impeller threads require no inserts or nuts. High efficiency and high head designs are also available.
7. Throatbush - wear is reduced and maintenance simplified by the use of tapered mating faces to allow positive accurate alignment during assembly and simple removal.
8. One-piece frame - a very robust one-piece frame cradles the cartridge type bearing and shaft assembly.
9. An external impeller adjustment mechanism is provided below the bearing housing for easy adjustment of impeller clearance.

Pump Driven Type
DC Type: The output shaft of a motor is directly connected to the input shaft of a pump via a pump coupler. This type of connection is suitable for applications where the speed of the slurry pump is the same as that of the motor.
CV Type: The pump is driven by a belt connected to the crankshaft of the engine. This way of connection allows for saving space, easy installation, and fast adjustment of pumping speed. The motor is fixed to the motor support frame which is located on the bearing support above the slurry pump.
ZV Type: Another type of belt drive that allows easy adjustment of pumping speed. The motor is directly fixed to the bearing support. This way of installation is suitable for motors with larger horsepower than is possible with CV type of installation. Due to the installation of motor onto the bearing support, this method helps save installation space.
CR Type: This type of belt drive makes it easier to adjust pumping speed. The installation allows both the motor and slurry pump to be fixed to the ground. The motor is installed to the side of the pump. This installation method is suitable for large-power motors.

For different duties, pump is named as High head pump, High pressure pump, Mineral processing pump, Mill discharge slurry Pump, Booster pump, Feeding pump, Tailing pump,Transfer pump Thickner Underflow Pump, De-watering screen pump, Pressure pump, Concentrate pump.
What Type of Pump is Best for Slurry?
In the world of slurry handling, choosing the right pump is crucial for efficient operation and optimal performance. With a wide range of pump options available, it's important to understand the different types and their suitability for slurry applications. In this article, we will explore the various pump options and highlight the best type of pump for slurry handling.
1.Centrifugal Slurry Pumps:
Centrifugal slurry pumps are widely recognized as the go-to choice for slurry transportation. These pumps use centrifugal force to propel the slurry, making them highly efficient and capable of handling abrasive and high-concentration slurry. With their robust construction and ability to handle large particle sizes, centrifugal slurry pumps are ideal for mining, mineral processing, and other industries where heavy-duty slurry handling is required.
2.Submersible Slurry Pumps:
Submersible slurry pumps offer the advantage of being submerged directly into the slurry, eliminating the need for priming and providing greater flexibility in installation. They are particularly useful in applications such as dredging, sand and gravel extraction, and underwater slurry pumping. Submersible slurry pumps are designed to withstand the harsh conditions of submersion and are highly efficient in handling abrasive slurry.
3.Piston Diaphragm Pumps:
Piston diaphragm pumps, also known as membrane pumps, are well-suited for handling highly viscous and abrasive slurries. These pumps use reciprocating pistons or diaphragms to create pressure and move the slurry. With their ability to handle thick and sticky slurries containing solids, piston diaphragm pumps find applications in industries such as chemical processing, wastewater treatment, and ceramics.
4.Peristaltic Pumps:
Peristaltic pumps, also called hose pumps, are known for their gentle pumping action and ability to handle shear-sensitive slurries. These pumps use rotating rollers or shoes to compress a flexible hose, creating a squeezing action that moves the slurry forward. Peristaltic pumps are widely used in industries such as pharmaceuticals, food processing, and water treatment, where precise and low-shear pumping is required.
5.Conclusion:
When it comes to selecting the best pump for slurry handling, centrifugal slurry pumps are often the preferred choice due to their efficiency, versatility, and ability to handle abrasive slurries. However, the specific application and slurry characteristics should be considered to determine the most suitable pump type. Submersible slurry pumps, piston diaphragm pumps, and peristaltic pumps offer viable alternatives depending on the requirements of the application. By understanding the strengths and capabilities of each pump type, you can make an informed decision and ensure optimal slurry handling in your operations.
