Axtron Grand Forest 800 GPD RO Booster Pump 24V

Axtron Grand Forest 800 GPD RO Booster Pump 24V

Every RO plant needs pressure. Reverse osmosis works by forcing water through the membrane, and without enough pressure behind it the membrane cannot reject salts properly — output drops, TDS climbs, and the plant looks like it is failing when the real problem is the pump.

The Axtron Grand Forest 800-G is a 24V DC diaphragm pump rated at 800 GPD, delivering 4.6 litres per minute at 120 to 140 PSI. It is the pressure stage for semi commercial plants, and we stock it at our shops in Multan, Lahore and Bahawalpur.

Specifications

Included: pump, wall mounting bracket, 2-pin connector lead.
Not included: transformer.

Which Plants Does It Suit?

This pump handles two configurations:

One 800 GPD membrane. The straightforward match — one pump, one membrane, sized together.

Multiple 400 GPD membranes in a single plant. Where a plant runs paired 400 GPD elements, this pump supplies the pressure for both.

In practice that covers the middle of our semi commercial RO plant range. Plants in this bracket serve larger households, madrassas, schools and colleges — anywhere from fifteen to a hundred people drinking daily, and up to around two hundred in some installations. Across Multan, Lahore and southern Punjab, this is the size we fit most often in schools and madrassas.

Our semi commercial plants span 200 to 1000 GPD and pumps are matched across that range. If your plant sits at a different capacity, tell us the GPD and we will give you the right pump rather than the nearest one.

You Will Need a Transformer

This is sold as the pump alone. A 24V DC pump cannot run directly from mains supply — it needs a transformer to step 220V AC down to 24V DC.

If you are replacing a failed pump, your existing transformer will usually serve, provided it is rated for this pump's draw and is itself in good condition. Transformers do fail, and a weak one causes exactly the symptoms people blame on the pump: low pressure, poor output, a pump that runs hot or cuts out.

If you are building a new plant or your transformer is suspect, ask us and we will supply the matching unit. Bring your existing one into any of our shops and we will test it, or send a photo on WhatsApp.

About the "Residential" Label

The pump body carries a line reading "designed for residential reverse osmosis system." That wording is standard across this class of pump and refers to small-system duty rather than heavy industrial service.

At 800 GPD and 120–140 PSI, it is correctly matched to semi commercial plants in the 400 to 800 GPD range. A larger commercial plant needs a high-pressure pump, not this one, and we will tell you so if that is what you are running.

Buy in Multan, Lahore or Bahawalpur

We stock this pump at all three of our shops. Walk in with your old pump or a photo of your plant and our team will confirm the match before you buy — it takes two minutes and saves you ordering the wrong rating.

Multan — Akbar Road, Tipu Sultan Colony. Customers from across southern Punjab collect parts here rather than wait for delivery.

Lahore and Bahawalpur — same stock, same advice, same price.

If you cannot visit, we deliver nationwide with cash on delivery. Karachi, Islamabad, Faisalabad, Rawalpindi, Gujranwala, Peshawar and everywhere between.

Fitting and Service

In Multan, Lahore and Bahawalpur our technicians fit and test pumps on site, including on plants supplied by others. If your plant has lost pressure and you are not certain whether the fault is the pump, the transformer or the pre-filters, we will diagnose it rather than sell you a part you may not need.

Outside these three cities we deliver nationwide and help you work through it by phone or WhatsApp. Most pump replacements are straightforward, and we post fitting videos on our Facebook and Instagram pages.

Getting Longer Life From Your Pump

Keep the pre-filters clean. A pump pulling through a clogged sediment cartridge works far harder than it should. The same neglect that chokes membranes burns out pumps, for the same reason. PPF cartridges need changing every 15 to 30 days depending on your water — see our semi commercial filters.

Do not let it run dry. A diaphragm pump needs water through it. Running dry, whether from supply failure or an empty feed tank, damages the diaphragms quickly. In areas with irregular supply this is the most common avoidable cause of pump failure we see.

Mount it properly. The bracket is supplied for a reason. A pump left loose on the floor vibrates, stresses its fittings and loosens connections over time.

Watch the duty cycle. The label notes that duty cycle varies with load and ambient temperature. A pump running continuously through a Multan summer works considerably harder than one cycling normally in winter.

Signs the Pump Is Failing

Pressure dropping. The clearest sign, and the one that shows in your output first.

Noise changing. Diaphragm pumps get louder and rougher as they wear.

Running hot. Some warmth is normal. Too hot to hold comfortably is not.

Not starting, or cutting out. Check the transformer before condemning the pump — a failing transformer produces the same symptoms and costs far less to replace.

Before replacing a pump, check the pre-filters. A blocked sediment cartridge starves the pump and mimics pump failure. We have had plenty of customers ready to buy a new pump when a cartridge change solved it.

Frequently Asked Questions

Does this come with a transformer?

No. The pump, mounting bracket and connector lead are included. A 24V DC pump needs a transformer to run from mains supply — ask us and we will supply the matching one.

Can I buy this pump from your shop in Multan?

Yes. We stock it in Multan, Lahore and Bahawalpur. Bring your old pump or a photo of your plant and we will confirm the match before you buy. We also deliver nationwide with cash on delivery.

Will it fit my RO plant?

If your plant runs one 800 GPD membrane or multiple 400 GPD membranes, yes. Tell us your plant capacity and we will confirm.

What pressure does it produce?

120 to 140 PSI, with an open flow of 4.6 litres per minute.

The label says residential. Can I use it on a commercial plant?

On semi commercial plants in the 400 to 800 GPD range, yes — that is what it is matched to. Full commercial plants need a high-pressure pump instead.

My pump is not starting. Is it broken?

Check the transformer first. A failing transformer causes the same symptoms as a failed pump and is cheaper to replace. Also check your pre-filters, since a blocked cartridge starves the pump.

How long does a booster pump last?

There is no fixed figure. It depends on running hours, water quality and how well the pre-filters are maintained. Pumps on plants with cartridges changed on schedule last considerably longer than those pulling through clogged filters.

Do you deliver outside Multan, Lahore and Bahawalpur?

Yes, nationwide with cash on delivery. On-site fitting and service visits are limited to our three shop cities, but we support installation anywhere in Pakistan by phone and WhatsApp.

Where is it made?

Vietnam.

Can I fit it myself?

Yes. Mount it on the bracket, connect inlet and outlet the right way round — the pump head carries a flow arrow — and wire it through your transformer. Our teams will fit it for you in Multan, Lahore and Bahawalpur.
