Lowara Pump Repair & Booster Pump Service

Get In Touch

Mawdsleys Pump Services has been repairing and servicing Lowara pumps across the South West and South Wales for over 30 years. Whether you need a Lowara booster pump service, a fault diagnosed and repaired, or a full overhaul of a Lowara pumping system, our in-house engineers carry out all work directly — from our Bristol workshop and on-site across the region.

We work with Lowara pumps across a wide range of applications: booster sets in commercial buildings, hotels and apartment blocks; sewage and wastewater submersibles; clean water supply pumps; and industrial circulation systems. Whatever the Lowara model, whatever the fault, call us first.

Lowara Booster Pump Service

Lowara is one of the most widely installed booster pump brands in commercial and industrial premises across the South West. Their e-SV, HM, HMV, SB and FC series booster sets are found in hotels, apartment blocks, hospitals, office buildings and manufacturing facilities — and when they develop a fault, they need an engineer who knows the platform.

A Lowara booster pump service from Mawdsleys covers:

Inlet strainer inspection and cleaning — a blocked strainer is a common cause of reduced output and cavitation damage on Lowara multi-stage sets
Pressure switch and pressure sensor testing — verifying cut-in and cut-out settings and calibrating where pressure delivery has drifted from the design specification
Non-return valve check — testing for correct seating and absence of leakage on the discharge side
VSD/inverter inspection (where fitted) — checking drive settings, fault history and cooling fan condition on variable speed Lowara booster sets
Expansion vessel pre-charge pressure check — ensuring correct pre-charge to prevent short-cycling, a common accelerator of Lowara motor wear
Motor insulation and current draw testing — identifying winding deterioration before it causes motor failure
Control panel inspection — verifying alarm functions, auto-changeover (on twin-pump sets) and telemetry connections
Full system pressure and flow test — confirming the system is delivering to its design specification at all outlets
Written condition report — a full record of findings and any parts or follow-up work required

Lowara Pump Repair

When a Lowara pump develops a fault — a drop in pressure, a tripped overload, a failed motor or a seized impeller — Mawdsleys provides Lowara pump repair across Bristol and the South West on a 24/7 basis.

Common Lowara pump faults we repair:

Pressure loss or no output — caused by impeller wear, a failed seal, limescale buildup on multi-stage impeller stacks, or a failing pressure sensor
Pump tripping the overload relay — usually indicates a blockage, a bearing failure or a motor winding fault
Motor failure — motor rewinding is carried out in our Bristol workshop (home to a dedicated rewind shop), restoring Lowara motors to original specification at a fraction of replacement cost
VSD fault or alarm — drive faults on variable speed Lowara booster sets diagnosed and resolved by engineers familiar with the platform
Noise and vibration — caused by bearing wear, cavitation or loose pipework fixings; identified and resolved during a repair visit
Pump running but pressure too low — often a worn impeller or incorrect pressure switch calibration; our engineers carry calibration equipment on every visit

Our Lowara repair process:

Most Lowara pump repairs are completed on-site in a single visit. Where a pump requires strip-down, motor rewinding or bench testing, it is transported to our workshop at Kingsland Trading Estate, Bristol, and returned to site ready for reinstallation. We provide a realistic timeline upfront and keep you updated throughout.

Flygt Pump Repair & Servicing

Alongside our Lowara expertise, Mawdsleys provides Flygt pump repair and servicing for submersible sewage, wastewater and stormwater applications across the South West and South Wales. Flygt submersible pumps — part of the Xylem group — are widely used in municipal and industrial wastewater management, and our engineers have extensive hands-on experience with the N, NP, C and D series models.

For emergency Flygt pump repair, we operate 24/7 with a dedicated emergency Flygt pump servicing line.

Lowara Pump Repair & Service FAQs

Are you an authorised Lowara service centre?

Mawdsleys is an independent pump repair specialist with over 30 years of experience working with Lowara products. We are not a Lowara authorised distributor, but our engineers have extensive hands-on experience with the full Lowara range — including booster sets, submersibles and circulation pumps — and we carry common Lowara parts in stock. For many clients, our response times and regional coverage make us the faster, more practical choice than the authorised service network.

What Lowara pump models do you repair?

We repair all Lowara models across their commercial and industrial ranges, including the e-SV multi-stage vertical pump series, HM and HMV horizontal multistage sets, SB stainless steel booster pumps, FC series, DOC and DOMO submersibles, and Lowara solar and variable speed pump systems. If you have a model not listed here, call us on 0117 954 8030 and we’ll advise you directly.

Do you carry Lowara spare parts?

We stock a range of common Lowara consumable parts — including mechanical seals, impellers, pressure switches and control components — at our Bristol workshop, reducing lead time on the most frequent repair requirements. For less common parts, we source from our supplier network and will give you a realistic delivery estimate before any work is confirmed.

How quickly can you attend a Lowara pump breakdown?

We operate 24/7, 365 days a year for emergency call-outs, including bank holidays and Christmas. For non-emergency Lowara pump repairs and service visits, we typically schedule within a few working days depending on location. Call 0117 954 8030 and we’ll give you an honest timeframe based on your location and the nature of the fault.
