Structural characteristics
Vertical (Horizontal) Pipeline Centrifugal Pump Single-stage circulating pump fitted with standard motor and mechanical seal. Adopt pull-out structure for easy maintenance without pipeline disassembly. Available in carbon steel and stainless steel materials. Compact structure, stable running, low noise. Widely applied in building water supply, industrial circulation, boiler water supply and environmental water treatment.
Operating Pressure-Temperature Range
Operating Pressure-Temperature Range These curves show the maximum permissible working pressure at various liquid temperatures. Standard model applies to -10°C ~ 80°C medium, and customized high-temperature model supports medium temperature up to 120°C. Operating pressure should not exceed the curve limit.
Application Scope
FAQs：
1
What are the main differences among W, WR, WH, WB and WD models?
Model W is horizontal clean water pump for normal-temperature clean water; WR is hot water pump for high-temperature hot water circulation; WH chemical pump for corrosive liquid; WB pipeline oil pump for gasoline, diesel and similar oil products; WD low-speed pump for sites requiring low noise. They differ in applicable media and temperature range. Please confirm medium and temperature before selection.
2
What is the allowable temperature range of the conveyed medium?
Medium temperature for W clean water pump ≤80℃; WR, WH and WD models: -20℃~120℃; WB oil pump: -20℃~120℃. Long-term operation beyond the temperature range is forbidden to prevent premature seal failure.
3
Is daily maintenance complicated? Can we replace spare parts without dismantling the whole pump?
Maintenance is convenient. Wearing parts such as mechanical seals and bearings can be replaced without full pump disassembly, reducing maintenance time and cost. Pump casing material can be carbon steel or stainless steel to meet different anti-corrosion requirements.
