Pump Systems
Hydro-pneumatic pump systems sized to your site's real head, flow, and duty cycle — not a one-size-fits-all unit.
Why ClairHydra Pumps
Engineered for Real Building Demand, Not a Nameplate
Constant-Pressure Delivery
VFD-controlled models match motor speed to real-time demand for steadier delivered pressure than fixed-speed operation.
Reduced Hydraulic Shock
VFD's smooth ramp-up avoids the instant-on surge of fixed-speed starting, easing stress on pipework and fittings.
Stainless Steel Hydraulics
SS304/SS316 hydraulic options resist corrosion across a range of water conditions and applications.
Configurable Motor Protection
Dry-running, phase-loss, and electrical overload protection available as optional, site-configured additions — not standard on every unit.
Motor Power Range
Continuous-Duty, Two-Pole Motor Class
Motor Protection Rating

Pump Body and Hydraulics materials come from different parts of the source spec sheet (the System Selection Snapshot table vs. the Features section), which don't fully agree with each other on material options — shown exactly as each section states, not reconciled into one figure.

H = head, in meters, at the given flow rate. Performance data based on water at 20°C, 50Hz — validate against actual head, flow, and NPSH requirements before final selection.
*Warranty covers manufacturing defects on non-consumable parts only; extended coverage terms set by the authorized dealer.
Site Assessment
What We Assess Before Sizing Your Pump
A pump spec sheet alone can't size your system — it depends on data specific to your building. This is what the free site assessment gathers before any quotation.
Required flow rate and peak demand pattern
Static head, friction losses, and required terminal pressure
Number of floors/outlets and diversity factor
Available power supply, duty cycle, and application criticality
