Product Overview

   The PNL series of vertical submersible slurry pumps are single-stage, single-suction slurry pumps available in both vertical and horizontal designs. They are primarily used for conveying liquids such as water, oil, acidic and alkaline solutions, emulsions, suspension emulsions, and liquid metals. They can also handle liquid-gas mixtures as well as liquids containing suspended solids. These pumps are suitable for transporting sand, gravel, slurry, and sewage in industries including infrastructure construction, geology, mining, environmental protection, and chemical engineering. They feature long service life, simple structure, and reliable operation.

  The PNL vertical slurry pump is used in industries such as mining, metallurgy, municipal construction, chemical engineering, and textile dyeing to convey various slurries containing flowing sand, small mud lumps, and other solid particles. It can also be employed for the suction and delivery of river silt, pond sediment, manure, and slurry-like beverages in rural areas. Additionally, it is suitable for transporting mineral slurry in urban and industrial settings, as well as for underground extraction of yellow sand and mud. Depending on the medium being pumped, the wetted parts can be made from a variety of materials, making this pump ideal for handling abrasive or corrosive slurries. The maximum concentration of solids that can be conveyed ranges from 50% to 60% by weight. Among these pumps, the 3PNL and 4PNL slurry pumps are essential equipment for drilling operations in foundation engineering projects and can be used by sectors such as mining, metallurgy, and power plants to transport two-phase fluid mixtures consisting of both solids and liquids.

Product Parameters

 

Features of the PNL vertical submersible slurry pump:

1. PNL submersible Mud pump The wear-resistant components in the flow passage are made of wear- and corrosion-resistant cast iron, ensuring a long service life.

2. The clearance between the impeller and the guard plate can be adjusted promptly to maintain high operational efficiency.

3. The bearings of the above-mentioned pump type are directly mounted inside a horizontally split support frame, making disassembly and inspection convenient and allowing for timely adjustments. Additionally, a water-cooled serpentine tube is installed within the oil sump, thereby improving the operating conditions of the bearings.

4. The pump body above the pump is relatively large and features a split structure, making disassembly, assembly, and maintenance convenient.

Mud pump installation:

1. Preparations before installation
(1) Inspect the pump and motor to ensure there is no damage incurred during transportation and loading/unloading.
(2) Prepare the tools and lifting equipment, and inspect the machine foundation according to the drawings.
2. Installation Sequence
(1) The entire pump set has already been assembled on-site with the motor installed. When leveling the base, there is no need to remove the pump and the motor.
(2) Place the base on the foundation and prepare it for leveling before filling with concrete.
(3) Use a level to check the horizontal alignment of the base by referencing the pump’s discharge port plane. After leveling, install the anchor bolts and then pour concrete around the anchor bolts.
(4) Place the steel ruler on the coupling (measuring in the up, down, front, and back directions) to check whether the shaft lines of the pump and the motor are aligned.
(5) After the concrete around the anchor bolts has completely hardened, tighten the nuts on the anchor bolts. Finally, check the levelness of the entire unit again. If there is even a slight unevenness, use wedge-shaped shims to adjust the level.
(6) Install the suction and discharge pipelines. When connecting the pipelines to the pump, be careful not to allow the weight and pressure of the pipelines to be transferred onto the pump, as this could cause deformation of the pump.
(7) Clean the environment and maintain hygiene.

Mud pump maintenance and upkeep:

(1) Check whether there are any loose connections at the pump and pipeline joints. Manually rotate the pump to see if it operates smoothly, then verify the motor’s rotation direction.
(2) Connect the flushing cooling water at the pipe joint in the mechanical seal chamber.
(3) Fill the pump with priming water.
(4) Close the gate valve on the outlet pipe and the outlet pressure gauge.
(5) Start the motor. Once the pump is running normally, open the outlet pressure gauge and gradually open the gate valve until the gauge indicates an appropriate pressure. At the same time, monitor the motor’s load condition.
(6) As much as possible, keep the pump’s flow rate and head within the ranges indicated on the pump’s nameplate, ensuring that the pump operates continuously near its high-efficiency point to achieve the greatest energy-saving effect.
(7) During operation, the bearing temperature rise of the pump shall not exceed 35℃ above the ambient temperature, and the maximum temperature shall not exceed 80℃.
(8) During operation, if any unusual noises are detected, the pump should be stopped immediately to investigate the cause.
(9) When the pump is to be shut down, first close the gate valve and the pressure gauge, then stop the motor.
(10) Pay attention to the lubrication condition of the bearings and regularly inject grease into the bearing housing.
(11) When using the pump during cold winter months, after stopping the pump, be sure to unscrew the drain plug at the bottom of the pump body to completely drain the water, thus preventing freezing and cracking.
(12) For long-term use, the pump must be completely disassembled, thoroughly dried to remove all moisture, and then reassembled after applying grease to moving parts and joints. It should then be stored properly.

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.
