No app. No leaks. Just a real seal.
Sick of pumps that leak, die early, or never actually fit?
You have tried the cheap one that stopped working after a fortnight. You have read the horror stories about pumps losing suction mid-feed. You have bent over the sink and watched an afternoon's milk go down the drain because the seal gave way.
Lonva Latch is built to actually last, with a closed anti-spill valve and 5 flange sizes so it fits from day one, no trial and error, no gamble on whether it survives the month.
You've already tried the usual fixes. Here's why they failed:
✕
Cheap Amazon pumps
The suction goes, the seal wears out, and most give up within weeks. You are back to square one, minus the money.
✕
£250+ premium brands
Barely more output for double the pumping time, and replacement parts cost almost as much as buying a new pump.
✕
Manual or handheld pumps
Fine for one quick session at home, useless for a working day of back-to-back feeds with a hand free for anything else.
✓
What actually works: a proper seal, real suction, built to last
Latch's 5 flange sizes and closed duckbill valve give you a proper seal, and the 325mmHg motor gives you 12 real suction levels. You just clip it in and go.
The simple idea
The 5-flange system that finally gets you a real seal
SecureSeal™ Fit System pairs 5 flange sizes with a closed duckbill valve so suction stays sealed against your skin, not leaking into your bra.
1
5 flange sizes, so one of them actually fits
Most brands ship one size and hope. Latch includes 17/19/21/24/27mm flanges so you get a proper seal from the first try, not weeks of trial and error.
2
12 suction levels, 4 modes, 325mmHg
Dial in from a gentle let-down massage to a full 325mmHg feed. Real hospital-grade pull, not a weak buzz.
3
A closed duckbill valve that actually stays closed
A one-way anti-backflow valve and an upright dust-cap design mean no spilled milk down your top and no leaks when you bend over.
Suction and seal both fade over months of daily use, on any pump. Wash all parts after every session and replace the duckbill valve every few months to keep the seal strong. If you have any pre-existing breast or nipple condition, check with your midwife or GP before use.
Life after Latch
Say goodbye to leaks and dead-motor panic. For good.
You deserve a pump you can trust through every feed. This is what switching actually gets you.
A feed that does not end in a wet top
A proper seal and closed valve mean what you pump stays in the bottle, not down your front or wasted in the wash.
Both hands free, actually free
Clip it in under your top and get on with the school run, the laptop, or five minutes sitting down. No tube, no wall socket.
Quiet enough for night feeds
Under 30dB means you can pump next to a sleeping baby, or in a meeting, without anyone noticing.
A pump that is still going in month four
No dead motor at week six, no chasing customer support. Built to survive daily use, not just the return window.
What to expect
What switching to Latch actually feels like, week by week
No miracle claims, just what our customers actually tell us.
First feed
You feel a real seal from the first try
One of the 5 flange sizes fits properly, so you are not fighting the pump on day one.
Week 1–2
Hands-free actually means hands-free
You are pumping while making lunch, replying to messages, or just sitting down for a minute. That is the whole point.
Week 4
You stop thinking about it dying
No dropped suction, no random shutdowns. It just works, session after session.
Week 8
Still going, still sealing properly
The stage most cheap pumps have already failed by. A fresh duckbill valve every few months keeps the seal strong for the long run.
Everything a real wearable pump should have
Premium nursery-ready design
5 flange sizes, one proper fit
17/19/21/24/27mm ship in every box, so you get a real seal without buying separate sizes and guessing.
Hands-free in seconds
Clips inside any nursing bra. No tubes, no wall socket, no holding anything through the whole session.
Closed duckbill valve, zero backflow
A one-way anti-spill valve and upright dust-cap design mean what you pump stays exactly where it belongs.
"Will this actually seal properly, or leak like the others?"
Fair question. Wearable pumps are everywhere on TikTok right now, and the seal is where most of them fall apart. Here is the honest, no-nonsense difference.
5 flange sizes, not a one-size-fits-none guess.
A leaking pump is almost always a fit problem, not a suction problem. 17/19/21/24/27mm ship in every box so you actually find yours.
A closed duckbill valve, not an open cup.
The one-way valve stops milk flowing back toward the motor and stops it spilling out when you bend over, something cheap pumps skip entirely.
12 levels and 4 modes, not one weak buzz.
Start on the gentle let-down massage mode, then step up to a real 325mmHg feed. Your call, every single session.
Still unsure? Suction naturally softens as valves wear, on any pump. Replace the duckbill valve every few months and the seal stays like new. Try it for 60 days.
Expert review
A maternity nurse explains why Latch works
She spends her days helping new mums through feeding in the first weeks back at work. This is the pump she recommends first.
Why a proper seal beats another £250 pump.
“I see mums who spend a fortune on premium pumps and still end up leaking through their top by the second week, because a seal problem does not fix itself with a bigger price tag. Latch is the pump I point them to: five flange sizes in the box, not one, and a closed valve that actually stays closed. A pump they trust enough to actually use beats an expensive one sitting in a drawer, the ones who switch come back pumping full sessions without the panic.”

The Lonva 60-Day Real Seal Guarantee
Order today and use it daily for 60 days. If you do not get a proper leak-free seal and real hands-free freedom, return it within 60 days for a full refund. No questions, no hassle.
Still deciding if Latch fits your routine?
Will it actually get a good seal, or will it leak?
Latch ships with 5 flange sizes (17–27mm) and a closed duckbill valve specifically so you get a proper seal from day one. Most leaking complaints with other pumps come down to the wrong flange size, not the pump itself.
How loud is it really?
Under 30dB on standard settings, quiet enough to pump next to a sleeping baby or during a work call without anyone noticing.
Do I need an app or Bluetooth to use it?
No. Latch runs entirely from the on-pump display, no app, no pairing, no account needed. Pick a mode and level and go.
How often do I need to replace the valve?
Every 2–3 months of regular use, the same as any pump. A fresh duckbill valve is the easiest way to keep the seal and suction strong.
How long does the battery last?
The 1200mAh battery gives roughly 7–8 pumping sessions per charge, with a 20-minute auto shutoff built in so you never overwork it by accident.
How does shipping work?
Most orders are processed within 24 hours. Tracking is provided after dispatch.
What if it's not right for me?
