Construction & Tunneling Pumping Solutions

Rotho peristaltic pumps handle the toughest construction materials - bentonite slurry, grout, shotcrete, and concrete additives - in demanding jobsite conditions.

Construction Pumping Challenges

Construction sites demand rugged, reliable pumps that handle abrasive, setting materials in harsh outdoor conditions. Bentonite slurries, cement grouts, and concrete additives challenge conventional pumps with abrasion, clogging, and crystallization.

Abrasive Materials: Sand, aggregate, and cement particles destroy seals and impellers
Setting Materials: Grout and cement can set inside pump housings causing failures
High Solids: Bentonite slurries contain 30-50% suspended solids
Jobsite Conditions: Pumps must operate reliably in dust, vibration, and weather
Variable Flow: Applications range from precise additive dosing to high-volume slurry transfer

Why Rotho for Construction

Purpose-built features for jobsite demands

Handles Heavy Slurries

Transfer bentonite, drilling mud, and cement slurries with solids content up to 50%. No impeller to clog, no seals to wear - just simple, reliable pumping.

50% solids handling
No clogging
Passes aggregate
Reversible for clearing

Won't Set Up Inside

Product only contacts the replaceable hose - no pump housing or mechanical parts exposed to cement. If material sets, simply replace the hose and continue working.

No pump housing contact
Quick hose replacement
Minimal downtime
Easy cleanup

Precise Additive Dosing

Accurately meter concrete additives, accelerators, and retarders. Linear flow-speed relationship ensures consistent batch-to-batch quality in ready-mix operations.

Accurate metering
Consistent dosing
No slip
Signal controlled

Rugged & Reliable

Simple mechanical design with minimal moving parts operates reliably in dusty, wet, and harsh jobsite conditions. Self-priming up to 29.5 feet eliminates priming problems.
