Draper Expert Dual High Volume High Pressure Grease Pump

The Draper Expert Dual High Volume / High Pressure Grease Pump (GP-DA5) is an innovative, professional-grade hand-operated grease pump that combines two distinct greasing modes in a single unit — giving operators the choice between high-volume delivery for fast routine greasing or ultra-high-pressure delivery for clearing blocked grease nipples and tough applications. Switching between modes is as simple as pulling the gun's double-action trigger the right way.

Supplied complete with a 5kg plastic grease bucket, drum cover, 1.5-metre high-pressure delivery tube, and 360° swivelling fitting, the GP-DA5 is ready to handle the full range of professional greasing tasks straight out of the box — anywhere, with no power supply required.

Two Greasing Modes, One Tool

The standout feature of the GP-DA5 is its double-action trigger, which gives the operator two distinct working modes on demand:

High-Volume Mode — 1.25g per shot For routine greasing of multiple grease points on vehicles, machinery, and equipment, high-volume mode delivers 1.25 grams of grease per shot — getting the job done quickly with minimal operator effort. Ideal for chassis greasing rounds, agricultural maintenance schedules, and any application where many grease points need to be serviced efficiently.

High-Pressure Mode — 0.45g at 69MPa (10,000psi) When a grease nipple is blocked, hardened, or fitted to a stubborn component, high-pressure mode delivers 0.45g per shot at an exceptional 69MPa (10,000psi) — more than enough pressure to clear blocked nipples, push grease through restricted galleries, and service components that lighter pumps simply cannot handle.

This dual-mode capability transforms greasing productivity. A blocked nipple that would normally mean replacing the fitting, sourcing a higher-pressure tool, or skipping the lubrication point altogether can simply be cleared with a few high-pressure shots, then serviced normally in high-volume mode — all without changing tools.

Key Features and Benefits

The Draper Expert GP-DA5 combines genuine dual-mode versatility with professional build quality:

• Double-action trigger for switchable high-volume or high-pressure delivery
• High-volume mode — 1.25g per shot for fast routine greasing
• High-pressure mode — 0.45g per shot at 69MPa (10,000psi) for clearing blocked nipples
• Portable, hand-operated design — no electricity or compressed air required
• 1.5-metre 1/2" internal diameter high-pressure delivery tube for working reach
• 360° swivelling fitting allows the gun to rotate freely without kinking or twisting the hose
• 5kg plastic grease bucket included for substantial working capacity
• Drum cover keeps grease clean and contamination-free between uses
• Suitable for grease up to NLGI 2 — covers the vast majority of automotive and industrial greasing applications
• Draper Expert range — engineered for the trade professional

The 360° Swivel Advantage

Anyone who's wrestled with a kinked grease hose while trying to align with an awkward grease nipple will immediately appreciate the 360° swivelling fitting on the GP-DA5. As the operator moves the gun to suit the angle of each grease point, the fitting rotates freely — preventing hose twist, reducing operator fatigue, and making it far easier to maintain a clean seal on the grease nipple. It's a small detail, but one that makes a significant difference on jobs with many lubrication points or awkward access.

Ideal Applications

The GP-DA5's dual-mode capability makes it exceptionally versatile across professional greasing tasks, including:

• Heavy goods vehicle (HGV) and bus chassis lubrication
• Agricultural machinery and tractor servicing — including stubborn pivot points
• Plant equipment and earth-moving machinery maintenance
• Trailer and articulated vehicle greasing
• Construction equipment lubrication
• Industrial machinery and conveyor maintenance
• Marine equipment greasing
• Workshop and garage daily greasing tasks
• Field maintenance and mobile servicing
• Servicing equipment with blocked or hardened grease nipples that lighter pumps can't clear

A core piece of equipment for mobile mechanics, fleet maintenance teams, agricultural engineers, plant maintenance technicians, HGV workshops, and any operation that needs reliable, versatile greasing capability without depending on compressed air or mains power.

When 10,000psi Really Matters

Anyone who works on commercial vehicles, agricultural machinery, or aging plant equipment knows the frustration of a blocked grease nipple. Grease hardens over time, contamination accumulates, and what should be a simple lubrication point becomes a barrier between you and the bearing or pivot that needs serving. Standard hand grease guns and pumps simply don't generate enough pressure to push through stubborn blockages.

At 69MPa (10,000psi), the GP-DA5's high-pressure mode delivers the kind of force that clears those blockages — saving the time, hassle, and cost of replacing grease nipples, and ensuring critical lubrication points actually receive the grease they need. For fleet maintenance operations and agricultural engineers, this capability alone can transform productivity.

Why Choose the Draper Expert GP-DA5?

Most hand grease pumps offer either high volume or high pressure — forcing the user to compromise depending on the type of greasing work they do most often. The Draper Expert GP-DA5 eliminates that compromise entirely with its dual-action trigger system, giving operators the right delivery mode for every situation, in a single tool.

For mobile mechanics, fleet maintenance teams, agricultural engineers, and any operation that handles a wide variety of greasing tasks — including the inevitable stubborn or blocked grease nipple — the GP-DA5 is genuinely transformative. The high-volume mode delivers fast, efficient routine greasing, while the 10,000psi high-pressure mode handles the tough jobs that would defeat lesser pumps.

Add in the 360° swivel fitting, 1.5m high-pressure delivery tube, complete kit with bucket and drum cover, and the build quality of the Draper Expert range — and the GP-DA5 emerges as one of the most versatile and capable hand-operated grease pumps on the market.

Backed by Draper Tools — one of the UK's most respected names in workshop and industrial equipment — the GP-DA5 is built to deliver reliable, dual-mode greasing performance year after year.
