Hot Water Pumps
Hot Water High Pressure Pump Series
Industrial Hot Water High Pressure Triplex Plunger Pumps (Up to 85°C)
WULI manufactures industrial-grade hot water high-pressure triplex plunger pumps engineered specifically for continuous high-temperature duty, thermal degreasing, CIP sanitation, and industrial washdown systems. Ranging up to 85°C water temperature rating, our pumps deliver stable hydraulic performance, low pressure pulsation, and exceptional service life for global OEMs, plant engineers, and industrial facilities.
Standard cold-water pumps often suffer from rapid seal deterioration, thermal expansion leaks, and pressure loss when exposed to high-temperature fluids. Selecting a purpose-built hot water pump ensures uninterrupted operation, reduces thermal wear, and protects downstream equipment in heavy-duty thermal cleaning systems.
How to Select the Right Hot Water High-Pressure Pump (4-Step Selection Process)
Selecting the correct hot water triplex plunger pump requires balancing manifold material, temperature capability, flow rate, and motor power to maximize cleaning efficiency while avoiding pump cavitation. Follow this technical guide:
- Step 1: Select Manifold Material Based on Fluid Chemistry
Determine chemical exposure and sanitary requirements. Choose Forged Brass (WT-2024F1) for general industrial hot water washing and fleet degreasing. Select AISI 316 Stainless Steel (WTS-2024F1) for chemical processing, mild acids, and food-grade CIP sanitation. Note that only the parts fluid passes through are constructed from 316 stainless steel. - Step 2: Verify Operating Temperature & Inlet Feed
Confirm continuous water temperature does not exceed 85°C. Hot water reduces fluid vapor pressure, making pumps more susceptible to cavitation. Maintain sufficient inlet pressure or feed with a booster pump to ensure smooth liquid delivery. - Step 3: Calculate Required Power Output (HP / kW)
Use standard hydraulic formulas to size your electric motor or combustion drive appropriately:Note: Always add a 10–15% power safety margin to compensate for mechanical drive friction and system losses.Imperial Formula: Electric Motor HP = [Flow (GPM) × Pressure (PSI)] / 1450Metric Formula: Required Power (kW) = [Flow (L/min) × Pressure (Bar)] / 400 - Step 4: Verify Drive Connection & Operating RPM
Select the appropriate drive style (solid shaft, hollow shaft, or motor flange coupling) and match pump operating speed (RPM) with your power source.

Frequently Asked Questions (FAQ)
Q1: What is the maximum continuous water temperature supported by WULI hot water pumps?
WULI hot water industrial triplex plunger pumps (such as WT-2024F1 and WTS-2024F1) are engineered specifically for continuous-duty operation up to 85°C (185°F), utilizing specialized heat-resistant seal packings and robust thermal expansion management.
Q2: When should I choose Forged Brass (WT-2024F1) versus 316 Stainless Steel (WTS-2024F1) manifolds?
Choose WT-2024F1 (Forged Brass) for standard industrial hot water washing, commercial vehicle fleet cleaning, and general workshop degreasing. Choose WTS-2024F1 (316 Stainless Steel) for food & beverage CIP sanitation, chemical processing, aggressive media, and strict corrosive environments.
Q3: How do you prevent thermal cavitation when pumping hot water up to 85°C?
Hot water reduces fluid vapor pressure and increases the risk of vapor lock or cavitation. To prevent this, ensure a positive inlet head pressure, utilize a dedicated supply booster pump, and maintain proper flow feed matching the pump's displacement capacity.
Q4: How do I calculate the motor power requirements for these hot water triplex pumps?
You can calculate required motor power using standard hydraulic formulas:
Imperial Formula: Electric Motor HP = [Flow (GPM) × Pressure (PSI)] / 1450
Metric Formula: Required Power (kW) = [Flow (L/min) × Pressure (Bar)] / 400
Always leave a 10–15% safety buffer for drive friction losses.
