Product Overview

  The AH and AHH horizontal wear-resistant slurry pumps are horizontal, vertically centerline, and feature a double-pump-casing design. The pump body and pump cover are equipped with replaceable metal liners made of high-chromium wear-resistant alloy material. These liners can be used until they are completely worn through, thereby extending the maintenance cycle and reducing operating costs. The pump’s discharge direction can be installed at any of eight different angles.

  The AH and AHH wear-resistant slurry pumps are cantilevered, horizontal centrifugal slurry pumps. They are suitable for conveying highly corrosive, high-concentration slurries in industrial sectors such as metallurgy, mining, coal, power generation, and building materials. This type of pump can also be used in multistage series configurations.

  The pump bodies of AH and AHH pumps are equipped with replaceable wear-resistant metal liners or rubber liners. The impellers are made of either wear-resistant metal or rubber. In AHH pumps, both the pump liner and the impeller are made exclusively of wear-resistant metal.

  The shaft seals of AH and HH pumps can be either packing seals or centrifugal seals. The discharge outlet of the pump can be installed and used at eight different angles, rotating in 45-degree increments as needed.

Product Parameters

Performance and Structure of AH and AHH High-Efficiency Wear-Resistant Slurry Pumps:

  Pump Body, Pump Cover, and Wet-End Components: This series of pumps is a horizontal, vertical-centerline, double-casing slurry pump. The pump body and pump cover are equipped with replaceable metal liners made of high-chromium wear-resistant alloy material. These liners can be used until they are completely worn through, thereby extending the maintenance cycle and reducing operating costs. The pump’s discharge direction can be installed at any of eight different angles.

  Bearing Assembly: The pump’s bearing assembly features a cylindrical design, which facilitates adjustment of the clearance between the impeller and the front guard plate and allows for complete removal during maintenance. The bearings are lubricated with grease.

  Shaft seals (seals): The pump’s shaft seal types include packing seals, impeller seals, and mechanical seals.

  Transmission methods include V-belt drive, elastic coupling drive, gear-reduction box drive, hydraulic torque converter drive, variable-frequency drive, and thyristor speed control. Among these, the V-belt drive options are CL, CV, CR, ZL, ZV, and ZR drives.

  Overall Performance: The pump features a wide performance range, excellent cavitation resistance, and high efficiency. Multi-stage series connection technology can be employed to meet the requirements of long-distance conveyance. A variety of metallic materials are available for the flow passage components, and their depth can be further increased. By offering multiple speed options and diverse design configurations, the pump operates reliably under various demanding working conditions. It boasts a long service life, high operational efficiency, and the ability to handle a wide range of harsh conveying environments.

Meaning of the model designations for AH and AHH high-efficiency, wear-resistant slurry pumps:

  For example: 150/100-AH

  150—Pump suction inlet diameter

  100—Pump discharge outlet diameter

  HH—High-Head Slurry Pump

  M, AH—Slurry Pump

Introduction to the Design of AH and AHH High-Efficiency and Wear-Resistant Slurry Pumps:

  AH-type slurry pump:

  For high-concentration, strongly corrosive slurry flows, the range is 40-80%.

  For medium concentration and medium-corrosivity slurry flow rates, the range is 40-100%.

  For low-concentration, low-corrosivity slurry flows, the range is 40-120%.

  AHH-type pump:

  For medium concentration and moderately corrosive slurry, the flow range is 40-80%.

  For low-concentration, low-corrosivity slurry flows, the range is 40-100%.

Q

What is your typical delivery time?

A

Models in stock can be shipped the next day at the latest. All others are custom-made, with lead times generally ranging from 7 to 90 days depending on the product size and project specifics. Please contact our sales manager for details: 0731-88632200 。

Q

Do you have centrifugal pumps in stock?

A

Centrifugal pumps come in numerous models and configurations. Except for a small number of high-volume, standard models that are in stock, the vast majority are not stocked and are customized products. We need to select a pump based on your site's flow rate, head, media temperature, pH value, and installation conditions, etc., to determine the pump model and configuration before we can submit an order to the factory for production.

Q

What information should I provide when requesting a quote?

A

Generally, to obtain an accurate quotation, we recommend providing us with the following information: pump flow rate, head, on-site operating voltage and frequency, temperature, pH value, and solid particle content of the fluid being conveyed, and on-site installation conditions (horizontal or vertical installation), etc.

If you are not sure, don't worry, our business managers will assist you in determining this.

Q

What products do you mainly produce?

A

Zhonglian Pump Industry manufactures various large industrial centrifugal pumps. Main products include: self-balancing multi-stage pumps, multi-stage centrifugal pumps, single-stage centrifugal pumps, split-case pumps, chemical pumps, submersible pumps, pipeline pumps, long-shaft pumps, condensate pumps, etc.

Q

Could you help me with the selection?

A

Certainly! If the water pump model is not selected accurately, there will be big problems. If you choose a smaller one, it won't meet your needs; if you choose a larger one, it will waste electricity and fuel, increasing your costs.

Q

Why is it so slow to get a price quote?

A

Because centrifugal pumps are non-standard customized products with many models, the price range is also very large. Even for the same model, the price difference is also very large due to different materials and configurations. Taking the most common water pump accessory—the impeller—as an example, the price of a stainless steel impeller is several times that of a cast iron impeller. Therefore, we need to clarify the relevant information to give you an accurate price. Normally, if you provide relatively comprehensive information, we can quote within 5 minutes.
