Filter press Pumps
The ZJR series horizontal filter press pumps are specifically designed for targeted industries and applications, and are available in both V-belt drive and direct-drive configurations. All Sunlike filter press pumps can be equipped with mechanical seal systems, with seal faces made of tungsten carbide or silicon carbide. Each pump is fitted with a pair of mechanical seals, which can be lubricated either by pressurized flush water or, depending on the specific model, through a closed-loop system — using natural circulation or forced circulation with a water/ethylene glycol mixture.The bearings are lubricated with either grease or oil.
Products detail
Structure Features
The ZJR series pumps are purpose-built for filter press systems and engineered to handle high-solids slurries as well as corrosive media with acidic or alkaline properties.
SAs a flagship product in the Sunlike portfolio, the ZJR series stands out in durability and reliability. Unlike conventional front-suction filter feed pumps, the ZJR’s side-suction design ensures the mechanical seal is only exposed to the inlet pressure, significantly extending seal life and reducing maintenance frequency.
For corrosive applications, the pump shaft and seal chamber can be manufactured from special corrosion-resistant alloys.
The ZJR series can be lined with high-chromium alloy, rubber, silicon-carbide ceramic, or stainless steel, ensuring superior wear resistance and longer operating life for our customers.

Common Problem
1. What is the main use of slurry pump?
Slurry pump is mainly used to transport liquid containing solid particles, widely used in mining, metallurgy, coal, electric power, chemical, building materials and environmental protection and other industries.
2. What is the working principle of the slurry pump?
The slurry pump inhales the slurry from the suction inlet of the pump body through the centrifugal force generated by the rotation of the impeller, and the slurry is discharged from the discharge outlet of the pump body through the diversion of the pump shell.
3. How to choose the right slurry pump?
The selection of slurry pump needs to consider the following factors:
The physical and chemical properties of the medium, such as temperature, viscosity, corrosion, etc
The size and concentration of solid particles
Required flow and head
Pump material and structure
4. What are the precautions for the maintenance and maintenance of slurry pump?
Check the wear condition of impeller, pump housing and shaft seal regularly, and replace the worn parts in time
Keep pump body and pipe clean to prevent impurities from entering pump body
Check and replace lubricating oil regularly to ensure the normal operation of bearings
Check the coupling of the motor and pump regularly to ensure that the connection is secure
5. What are the common faults and treatment methods of slurry pump?
The pump does not produce pulp or insufficient pulp: check whether the suction inlet is blocked, whether there is air in the pump body, and whether the impeller is worn.
Pump body vibration or noise: check whether the pump shaft is bent, the impeller is balanced, and the bearing is damaged.
Seal failure, leakage: check whether the seal wear, replace the seal in time.
