Constant Pressure Booster System

Name: Constant Pressure Booster System
Brand: Xinnian
SKU: XN-BP Series (non-negative pressure, VFD)

XN-BP Series (non-negative pressure, VFD)

The booster set comprises a VFD control cabinet, vertical multistage pumps, pressure transmitters and a stainless steel flow-stabilising tank; pump speed follows network pressure to deliver constant-pressure variable-flow supply. The non-negative pressure model connects directly to the mains, using inlet pressure to save 20–40 % energy without creating negative suction — ideal for high-rise buildings, residential estates and plant secondary boosting.

Key Features

VFD constant pressure control, pressure fluctuation within ±0.01 MPa
Non-negative pressure superposition uses mains pressure and cuts energy use significantly
Multiple pumps in parallel with automatic rotation — one failure does not stop supply
Dry-run, over-pressure and negative-pressure protection for safe operation

Technical Data

Flow range	5 – 200 m³/h
Head	20 – 150 m
Control	One VFD for multiple pumps or one VFD per pump
Flow tank	304 stainless steel, sized to flow
Pumps	Vertical multistage centrifugal, duty/standby or parallel
Protection	Dry-run, over-pressure, overload, negative pressure
