Case Study — City Water Treatment

From Shutdowns to Sleepless Nights — to 365 Days of Flow.

Inside a California water plant, one Graco SoloTech™ hose pump and Liberty CES turned an impossible chemical into a year-long success story.

The Frequency of Failure → The Flow of the Fix

A municipal plant’s calcium hydroxide kept hard‑setting on every pause. James Riggins stepped into the gap — and engineered it out of existence.

Crystallized Ca(OH)₂ clogging lines
01

Before SoloTech: when flow stopped, concrete happened.

A municipal facility used calcium hydroxide (Ca(OH)₂) for pH control. Its nasty habit: when it stops moving, it hardens like concrete.

  • Outages/pauses → slurry crystallizes inside hoses and valves.
  • Within hours: a chalky mass locks the pump solid.
  • Restarts = line openings, hose cuts, flushes, and overtime.
  • Multiple pump brands/types failed within months.

In plain language: the chemical kept killing pumps. Every outage froze the line; every freeze meant hours of digging, cleaning, and new parts.

02

In the gap: James reframed the problem.

Everyone treated it like “make the pump tougher.” James saw a chemistry + mechanics mismatch. Ca(OH)₂ doesn’t just clog; static = solid. Eliminate stagnation and friction — don’t just swap brands.

Diagnosis

Dead zones, valves, and multi‑roller friction created hot spots/air pockets that hardened to stone.

Principle

Keep it moving. One path, one squeeze, reversible flow. Clear without opening the system.

James’ action
Why it mattered
Sized hose & material for hydroxide service
Prevented swelling, heat, premature wear
Integrated BLDC motor controller
Smooth starts; speed tuning for gentle run/flush
Grounding & containment base
Safer maintenance; clean compliance
Reversible control logic
Back‑flush in seconds — no disassembly
Operator “keep‑moving” protocol
Prevents static hard‑set windows

SoloTech™ 30: single‑roller, 360° compression — motion by design.

  • One roller • one hose • one squeeze per revolution — less heat, no localized fatigue.
  • Thick‑wall engineered hose (EPDM/NBR) for abrasive, alkaline Ca(OH)₂.
  • Reversible — clear lines instantly when flow stops.
  • Self‑priming & high suction lift (≈29–33 ft) for reliable restarts.
  • No valves, seals, or glands to crystallize shut or leak.
  • Variable‑speed control — gentle dose or quick flush on command.
