CAT CLASS: HQ-10786

Up to 200 ft High-Head Pump

Up to 200 ft high-head pumps lift water from deep excavations, trenches, or sumps and push it vertically up to approximately 200 feet. This is the entry rung on the high-head pump ladder, suited to moderate-depth dewatering where standard trash or submersible pumps lack the head pressure required. For taller lifts or multi-storey discharge, the 200-400 ft band provides greater vertical capacity.

Spécifications clés

Spécification	Plage typique	Signification
Maximum Head	Up to 200 ft	Vertical distance the pump can lift water before losing flow.
Power Source	Electric (single or three-phase)	Most models in this class run on grid or generator power.
Application	Deep excavation, sump discharge	Designed for situations where vertical lift exceeds standard centrifugal pump capability.

Comment choisir

This size class is appropriate when the vertical discharge height ranges from approximately 50 to 200 feet — typical for deep foundation work, utility trenches, or moving water up two to six storeys. Jobs requiring less than 50 feet of head are often better served by standard submersible or trash pumps, which offer higher flow rates at lower pressures. When the lift exceeds 200 feet — such as deep shaft work, high-rise construction dewatering, or hillside discharge — the 200-400 ft High-Head Pump band delivers the necessary pressure without staging multiple pumps in series.

Ce que cette taille peut gérer

Dewatering a 60-foot-deep utility trench with surface discharge
Pumping groundwater from a basement excavation up to street level
Lifting water from a deep sump pit in a parking garage foundation
Discharging seepage water from a caisson shaft to grade
Moving water from a below-grade mechanical room to an upper-floor drain
Transferring collected water from a deep storm drain manhole to a municipal line

Sécurité et opération

Verify that actual lift height, hose friction loss, and flow rate align with pump curve to avoid dead-heading
Secure discharge hose against whip if the pump loses prime or shuts off under pressure
Ensure electrical connections are protected from moisture and comply with NEC wet-location requirements
Never operate dry; high-head pumps rely on water for motor cooling and seal lubrication

Transport et logistique

Compact enough to move by hand truck or small utility trailer in most cases
Electric models typically weigh under 200 lb and fit in a pickup bed or van
Hose and power cord add bulk; plan for separate transport of accessories

Alimentation

Requires 115V or 230V single-phase power, or 208-230V three-phase depending on model
Generator must supply clean, stable voltage to protect motor windings
Cord length and gauge must account for voltage drop over distance to the sump

Questions fréquentes

Can this pump handle solids or just clear water?

Most high-head pumps in this class are designed for clear water or very fine suspended solids; trash and slurry applications typically require different impeller designs and lower head ratings.

How is head capacity different from flow rate?

Head measures vertical lift capability in feet, while flow rate (GPM) describes volume moved per minute. As head increases, flow decreases along the pump curve; a 200 ft rated pump may deliver minimal flow at maximum head.

When should multiple pumps be staged in series versus moving to the next size class?

Staging pumps in series adds complexity and introduces failure points; if a single pump in the 200-400 ft class can meet the head requirement, it is typically the simpler and more reliable solution.
