PRODUCT HIGHLIGHT: TRUFLO DAP SERIES ANSI PROCESS PUMP

In this article, we’re shining a spotlight on the Truflo DAP Series ANSI Process Pump — a true workhorse designed to thrive in tough industrial environments.

Manufactured in the USA, Truflo specialises in high-performance ANSI and API chemical process pumps that are trusted around the globe for their quality, reliability, and long service life.

So, what sets the Truflo DAP apart in a crowded field of ANSI process pumps? Let’s take a closer look.

Purpose-Built for the Process Industry

The Truflo DAP Series is engineered to meet ANSI/ASME B73.1 standards, ensuring complete dimensional interchangeability with other ANSI pumps. That means hassle-free upgrades, easier installation, and minimal modifications to your existing system.

Whether you’re replacing aging assets or building out a new process line, the DAP Series is designed to integrate seamlessly.

Designed for Easy Maintenance

The DAP Series features a back-pull-out design, allowing maintenance crews to service the pump without disconnecting piping or motor alignments — a major time-saver on busy industrial sites.

Its standardised seal chamber accepts a wide range of mechanical seals and flush plans, giving you the flexibility to specify the best solution for your process conditions and site preferences.

Built for Demanding Applications

The Truflo DAP Series is made to perform under pressure — literally. It handles a broad range of fluids and process conditions across many industries, including:

• Chemical processing – Acids, caustics, solvents, resins

• Mining and minerals – Abrasive slurries, process water, tailings

• Pulp and paper – Black liquor, stock transfer

• Water and wastewater – Corrosive or chlorinated media

• Petrochemical – Hydrocarbons, fuels, and high-temperature fluids

Wherever reliability and efficiency are non-negotiable, the DAP Series delivers.

Built Tough, From the Inside Out

Not all ANSI pumps are built the same. The DAP Series features heavy-duty castings, oversized shafts, and high-spec internals to minimise vibration, extend equipment life, and reduce maintenance intervals.

Truflo ANSI Process Pump Standard Features Include:

• Back-pull-out design for simplified servicing

• Fully open, investment-cast impeller – Ideal for solids-laden or slurry applications

• Balanced impeller – Reduces vibration, extending seal and bearing life

• Large bearing oil reservoir – Improves cooling and lubricant life

• Magnetic oil plug – Captures metallic debris before it becomes a problem

• Bullseye sight glass – Makes oil level checks quick and visual

• Labyrinth bearing isolators – Help keep contaminants out and protect bearing integrity

• Large bore stuffing box – Accepts a wide range of seal types

Material Options for Every Application

Truflo offers a wide range of metallurgy options to suit corrosive, erosive, and high-temperature services:

• Ductile Iron (with standard 316SS trim)

• WCB Carbon Steel

• CF8 / CF8M Stainless Steel

• CD4MCu Duplex Stainless

• CN7M Alloy 20

• Hastelloy B & C

• Titanium

Whether you're pumping acids, slurries, hydrocarbons, or hot water, there's a DAP configuration to suit.

Performance Meets Versatility

With 22 pump sizes available — including low-flow models — the DAP Series can be customised to fit your exact system requirements.

Available Options Include:

• High-efficiency impeller trims

• Low NPSHr designs

• Base-mounted or close-coupled configurations

• Customisable seal support systems

• Compatibility with VFDs and soft starters

Key Performance Specs:

• Max Capacity: 4,840 GPM (1,100 m³/h) @ 1750 RPM

• Max Head: 760 ft (230 m) @ 3500 RPM

• Temperature: Up to 180°C (350°F) with high-temp options
