How to choose a pump for stainless steel tank water truck

By Pinky July 7th, 2026 14 views

If you need to purchase a stainless steel tank sprinkler truck, be sure to first understand the material of the stainless steel tank accessories, especially the stainless steel pump. If your sprinkler truck is used to transport tap water, lake water, and mild coastal seawater for export to Southeast Asia and Africa, you can choose the standard model: 304 stainless steel flow parts, pump housing cavity, impeller, pump shaft, inlet flange, 304 stainless steel, and cast aluminum shell shell
But if the purchased sprinkler truck is used for export to high salt island countries such as Saipan, you need to choose high-end customization: 316 stainless steel, complete set of overcurrent components upgraded to 316, including the shell, which is also made of stainless steel material

At present, the Weilong brand stainless steel sprinkler pump is recognized by customers for its quality in China
·Weilong brand sprinkler truck is a professional vehicle mounted pump manufacturer in China, an industry benchmark with high export recognition. Weilong has been focusing on vehicle mounted self-priming centrifugal pumps for more than 20 years, which comply with the national standard QC/T29114-93 "Technical Conditions for Sprinklers". The products are exported in bulk to Southeast Asia, the Middle East, Australia, Africa, and are used in conjunction with United Nations peacekeeping vehicles and military water supply vehicles. The recognition of overseas customers far exceeds that of miscellaneous pumps.
·Strict factory testing with extremely low failure rate. Each pump undergoes 72 hours of full load continuous testing before leaving the factory, with an overall failure rate of less than 0.5%. The designed service life is 8 years, which is 3-5 years longer than other brands of sprinkler pumps.
·The accessories are globally universal, with a full range of standardized parts including gearboxes, fluororubber seals, impellers, and bearings for worry free after-sales service. They can be purchased by overseas repair shops, and there will be no shortage of parts or idle vehicles, greatly reducing overseas after-sales costs.

The Weilong stainless steel sprinkler pump belongs to the vehicle mounted external hybrid self-priming centrifugal pump, which is matched with a 304/316 stainless steel tank sprinkler truck and driven by a chassis power take-off; The suffix N of the model represents that the overcurrent components are all made of stainless steel (impeller, pump shaft, pump casing inlet chamber), S represents right-hand rotation, N represents left-hand rotation, and is suitable for different chassis power take-off steering.

Taking the popular model 80QZB-60/90N as an example for disassembly:
1.80: Inlet diameter 80mm
2. Q: Automotive specific pump; Z: Self-priming; B: Strengthen the structure
3.60: Rated flow rate of 60m ³/h; 90: Rated head 90m
4. N: Left turn, all stainless steel overcurrent component
2、 Mainstream stainless steel models&compatible tanks/chassis

1）50QZ-8/25N / 50QZ-12/32N
Flow rate of 8-12m ³/h, head of 25-32m
Adaptation: 2-5 ton small Isuzu stainless steel sprinkler truck, small water transport truck
2) 65QZ-40/50N (basic model for foreign trade volume)
Flow rate of 40m ³/h, head of 50m, self-priming height of 6.5m
Adaptation: 5-8t stainless steel sprinkler, municipal disinfection and sterilization truck
3) 80QZB-60/90N (Industry leading high-end stainless steel pump)
Flow rate of 60m ³/h, lift of 90m, high-pressure water cannon range of 30-38 meters, self-priming 6-7 meters
Adaptation: 8-15 ton heavy-duty trucks, Isuzu, and Shaanxi Automobile stainless steel sprinkler trucks
4) 65QZB-50/110N (high voltage version)
Lift of 110 meters, long-distance road flushing, forest fire sprinkler
Suitable for large stainless steel water trucks weighing over 12 tons

3、 Classification of Stainless Steel Materials
1. Standard configuration: 304 stainless steel flow parts, pump casing cavity, impeller, pump shaft, inlet flange made of 304 stainless steel, and shell made of cast aluminum; Suitable for tap water, lake water, diluted disinfectant, mild coastal seawater, food grade rust free, rust free water bodies, mainstream municipal selection in Southeast Asia and Africa.
2. High end customization: A complete set of 316 stainless steel overcurrent components upgraded to 316, resistant to high chlorine seawater, high concentration disinfectants, and weak acid alkali cleaning solutions, specifically designed for ADR compliant stainless steel sprinkler trucks in Australia and the European Union.
3. Sealing standard: Fluororubber mechanical seal, which is corrosion-resistant and leak proof compared to ordinary rubber, with a lifespan doubled.
4、 Core structure and working principle
1. Composition: Stainless steel overcurrent pump body, closed stainless steel impeller, fluororubber seal, speed increasing gearbox, inlet and outlet flanges
2. Drive: The engine power take-off is directly connected to the gearbox, without the need for an external motor, and is installed in an integrated vehicle
3. Self suction principle (external mixing type): The pump chamber is pre filled with clean water, the impeller rotates to mix the air and water in the pipeline, and the gas-liquid separation chamber discharges the air. The suction is completed within 30 seconds without the need to install a bottom valve, making maintenance simple.
4. Multi water outlet function: matching with stainless steel sprinkler tip to realize multi mode switching of forward flushing, side sprinkling, rear spray and high-pressure water monitor.

Stainless steel pump vs ordinary cast iron sprinkler pump

comparative dimension	Weilong all stainless steel sprinkler pump	Ordinary cast iron sprinkler pump
Rust prevention ability	304/316 does not rust, and long-term seawater/disinfectant does not corrode	Extremely prone to oxidation, rust on the effluent after 3-6 months, clogging the nozzle
Media adaptation	Drinking water, seawater, disinfectant water, mild chemical liquids	Only clean tap water, long-term coastal/disinfection and sterilization use prohibited
Hygiene	No metal impurities precipitate, in line with overseas municipal drinking water standards	Rust pollutes water source, unable to be used as a drinking water delivery vehicle
service life	8-12 years, the inner wall is smooth and not prone to scaling	3-5 years, rust wears out and scrapped directly
Vehicle matching	Perfectly matched with stainless steel tank body, enhancing the vehicle's grade and premium	Only suitable for ordinary carbon steel sprinkler tanks
Applicable Market	Coastal cities in Australia, the Middle East, the Philippines, and Indonesia	Inland simple sprinkler truck

Unified material for the entire vehicle: stainless steel tank body+stainless steel pump, no corroded metal parts in the vehicle, high recognition from overseas buyers;
Coastal cities in Southeast Asia and Australia are prone to seawater flushing, road dust reduction, and cast iron pumps are highly susceptible to corrosion and water leakage;
Spraying disinfectant for epidemic prevention in cities in the Middle East and Africa, with stainless steel resistant to chemical corrosion;
Compliant transportation of drinking water: free from rust pollution, meeting the standards for municipal water supply and rural drinking water distribution;
Original Hangzhou Weilong factory, globally compatible accessories, convenient overseas after-sales maintenance;
High flow and high lift, high-pressure sprinkler tip for long-distance flushing, and dual-purpose for large-scale greening spraying.
7、 Key points for use and maintenance (with accompanying English manual)
Rinse the pump chamber with clean water at the end of each assignment, and drain any residual disinfectant and seawater;
When the temperature is below 0 ℃, the accumulated water in the pump must be drained to prevent freezing and cracking of the stainless steel chamber;
Do not dry run without water, dry grinding will quickly damage the stainless steel impeller and mechanical seal;
Check the fluororubber seals every 6 months and replace them promptly if they age;
Install a filter screen at the inlet to prevent sand and gravel from wearing the stainless steel impeller.
