  Product Description
The Shurflo 40x9 series represents a significant upgrade over the older 2095 models, built specifically for motorhomes and caravans that demand reliable freshwater delivery without the noise and rapid cycling issues that plague cheaper pumps. This 24v model delivers 11.3 litres per minute at 30psi, making it suitable for multi-fixture installations where you need consistent pressure across taps, showers and other outlets simultaneously. The four independent pump chambers work together to produce smooth, even flow rather than the pulsating delivery you get with basic two or three chamber designs.?

What sets this pump apart is the combination of thermal overload protection and genuine run-dry capability. If your freshwater tank empties whilst away from your van, the pump will not burn out. The adjustable pressure shut-off microswitch can be fine-tuned with a 2mm Allen key to match your system requirements, whilst the built-in bypass valve prevents the hammering noise that occurs when taps are opened and closed. It fits the same mounting footprint as the 2095 series, so retrofitting requires no cabinet modifications.?

The pump carries E8 electromagnetic compatibility marking for European use and all wetted materials meet KTW-BWGL standards for German drinking water regulations. At 1.8kg and measuring 205 x 125 x 106mm, it mounts in any orientation with a 2.7 metre self-priming capability. One consideration is the tapered 1/2 inch NPSM male thread fittings, which require proper tapered connectors rather than standard BSP adapters, and you must avoid using PTFE tape or jointing compound on threads as this voids the two year warranty.?

Frequently Asked Questions

Will this Shurflo 24v pump fit where my old 2095 series pump was mounted?
The 40x9 series was specifically engineered to occupy the identical mounting footprint as the 2095 series pumps, meaning the existing screw holes and cabinet space will align perfectly with this newer model. The dimensions of 205 x 125 x 106mm match the 2095 installation space, allowing you to remove the old pump and bolt this replacement directly into position without any cabinet modifications or new mounting plate fabrication.
Can this pump run dry without causing damage to the motor?
This pump includes genuine run-dry capability combined with thermal overload protection that automatically restarts once the motor cools. If your freshwater tank empties completely, the pump will continue running without suffering motor damage, though extended dry running should still be avoided where possible. The thermal protection cuts power before temperatures reach damaging levels, then automatically reconnects once safe operating temperature returns.
Why must I avoid using PTFE tape on the thread connections?
The 1/2 inch NPSM male threads on this pump are tapered, designed to seal metal-to-metal without requiring tape or jointing compound. When PTFE tape or thread sealant is applied to tapered threads, small pieces can break off during tightening and enter the pump chambers, where they block the diaphragms and valves. This type of failure caused by foreign material specifically voids the warranty, and proper tapered fittings like Shurflo swivel hubs create watertight connections through compression alone.
What does the adjustable pressure switch do and how is it adjusted?
The adjustable pressure shut-off microswitch controls the pressure at which the pump stops and starts, allowing you to calibrate the system for your specific plumbing layout and tap configuration. Adjustment requires a 2mm Allen key to turn the pressure adjustment screw clockwise to increase shut-off pressure or anticlockwise to decrease it. This adjustment helps eliminate rapid cycling when taps are barely open and prevents backflow into the freshwater tank when connected to mains pressure.
Is a water filter required with this Shurflo pump?
A 50 mesh inline strainer or proper pump filter must be installed on the inlet side between the freshwater tank and pump to prevent debris from entering the pump chambers. Without filtration, particles pass into the diaphragm assembly and check valves, causing the pump to lose pressure, fail to prime properly or stop pumping entirely even whilst the motor runs. Blocked filters are one of the most common causes of poor flow and should be checked regularly, particularly after filling from questionable water sources.
What is the advantage of four chambers compared to two or three chamber pumps?
Four independent pump chambers deliver water in overlapping pulses that combine into smooth, continuous flow rather than the noticeable surge-and-pause pattern from two or three chamber designs. Each chamber operates on a different stroke cycle, so whilst one chamber is on its intake stroke, others are pushing water through the outlet, effectively eliminating the pulsating delivery that causes taps to splutter and creates vibration noise throughout the plumbing system. This design also reduces the rapid on-off cycling that shortens pump lifespan in basic models.
Does this 24v pump draw less current than an equivalent 12v model?
The 24v version draws approximately half the current of an equivalent 12v pump delivering the same flow rate and pressure, because electrical power equals voltage multiplied by current. Whilst a 12v Shurflo pump typically draws around 7-8 amps, this 24v model draws approximately 4 amps maximum to produce similar output. This reduced current allows you to use lighter gauge wiring over longer distances with less voltage drop, making the 24v pump particularly suitable for larger motorhomes where the pump mounts far from the battery bank.
What does E8 electromagnetic compatibility certification mean for this pump?
The E8 mark confirms this pump meets European electromagnetic compatibility standards, meaning it neither produces electrical interference that disrupts other devices nor suffers interference from external sources. For motorhome and caravan owners, this certification matters because the pump motor will not cause static or buzzing through entertainment systems, will not interfere with navigation equipment or radio reception, and will function properly near inverters, battery chargers and other electrical equipment. All 40x9 series pumps carry this certification specifically for the European recreational vehicle market.
