FAQ

We manufacture our slurry pumps with raw materials like chromium, manganese, copper, silicon, molybdenum, nickel, iron, etc. In high chrome alloy (KmTBCr26) the chrome alloy content should not be less than 20%. Similarly nickel content should be 5%.

The ideal hardness for high chrome alloy material should be 56HRC to 60HRC to get good hardness and wear-resistant capabilities.

The pump motors are not waterproof. They need to be placed on land, outside the water. But the pump can submerge into the water during work. Also, the motors need to be fixed to a solid base to prevent it from falling to the water.

As the major axis length is fixed, installing pumps can be difficult and the flexibility of operation can be restricted.

We suggest you use two pumps alternatively. We also install nets on the inlet so that impurities can't go inside the pump.

Desulphurization pumps are cantilever type single-stage single-suction centrifugal pumps.

It is designed to transport corrosive medium containing fine particles.

Desulphurization pumps are made with UHMW-PE plastic material, which has high corrosion resistant capabilities. These pumps are highly abrasion resistant, impact resistant (especially the low-temperature impact resistance) and corrosion-resistant.

It's crucial to know the viscosity of the fluid before you buy a pump. If the fluid's viscosity is high then it requires powerful pumping equipment. If the viscosity is lower, the pump power can be minimized.

There are mainly four types of slurry pumps. These seals are used in different applications.

• Packing Seal: These types of seals need seal water and work best at a pressure of 35KPa, which is more than discharge pressure. These are low-cost and easy to maintain. But it also leaks a little during operation.
• Expeller Seal: These seals are superior to packing seals and can achieve no leaks. But expeller seals are not suitable for high pump chamber pressure or high suction.
• Expeller with packing seal: It's an enhanced version of expeller seal. It has four packing rings instead of two in the expeller seal. It needs seal water for some applications and the seal water pressure needs to be 70% of the discharge pressure.
• Mechanical Seal: This is the most efficient type of seal and the most expensive. Mechanical seals have a sealing gap which is positioned at 90 degrees to the shaft axis. These types of seals are highly durable and low-maintenance.

Centrifugal Seal (Expeller):
A centrifugal seal, or expeller, has no water flush and can seal many slurry pump applications with zero leakage using only grease lubrication. This is a no cost adder option on any pump where applicable.

Gland Seal:
Full flush gland seals are available to flow over the shaft sleeve and through the stuffing box to prevent media from escaping the pump housing. These seals provide excellent sealing properties with minimal cost and maintenance to the seal.

Mechanical Seal:
Customized mechanical seals solutions can be found for many applications where water flushing or grease-lubricated expellers are not options. We only apply mechanical seals specifically designed for abrasive and heavy-duty jobs.

Custom Seals:
We offer many different varieties of the above seals to include low-flow flush seals, water-flushed mechanical seals, and a variety of expeller arrangements. Call us today to find out more.

1. The rubber suction seal ring. This side should touch the throatbush. The fillister should match the bulge of the throatbush.

2. The bulge of the throatbush has its processing exactness limitation. Sometimes, it could not match the seal ring very closely, which may lead the leakage. Under this situation, we use another thin rubber piece.

3. Get the round ring from the thin rubber piece. Make the rubber circle ring match the fillister of the suction seal ring well, the frame and the dimensions. Put the circle ring into the fillister of the suction seal ring and put the complete one on the throatbush.

4. We are sure the leakage is just due to the suction seal ring. Therefore, we offer the solutions of the problem this way how to adjust slurry pump impeller.

1. You need know your flow (m³/h)
Flow rate means how much water you want to pump per hour.

2. You need know your head request (meter)
Head means how far or how high you want to pumping.

• The head = vertical length + pipeline lose.
• Vertical length = the distance from inlet water level to outlet water level.
• Pipeline lose = per 100m pipe will lose 2 ~ 3m head. (If you need install the valve into the pipe, please tell us, it also effect the head.)
• The height is distance from the base of the pump to the mounting point of a project.
