Bilge, ballast, fresh water, sea water, fuel transfer and cargo pumps, plus mechanical seals, impellers, bearings and repair kits delivered to vessels at U.S. ports.
Alpha Ship Supplies is a marine pumps supplier for commercial vessels calling at ports across the United States. From a replacement bilge pump to a mechanical seal for a cargo pump, our Houston team identifies the right unit or part by maker, model and serial number, quotes it alongside your other stores, and delivers it to the vessel at its berth. Pump requirements are matched to the equipment on board before we quote, so the part that arrives is the part that fits.

A pump failure on board is rarely an isolated problem. A worn seal on a sea water cooling pump can take an auxiliary engine out of service, and a failed bilge or ballast pump can hold up a port state inspection. The fastest fix is getting the correct unit or spare on board the first time, which starts with identifying exactly what is installed.
Chief engineers and technical superintendents send their pump requisitions to us because:
Because pump spares travel with the rest of your requisition, there is no separate courier to chase and no extra delivery for the crew to receive during a busy port call. One coordinator tracks every line from quotation to the signed delivery note.
Send the nameplate details, failed part and the vessel’s next port. We confirm what can reach you before sailing.
Commercial vessels carry dozens of pumps, each sized for one duty. We supply complete units and spare parts for:
Centrifugal, gear, screw and diaphragm designs are all covered. Tell us the duty and the installed model and we will quote the matching unit or parts.
If the installed model is obsolete, we can help identify a modern replacement with matching performance and connections, and list any adapter parts needed for the swap.
Tankers and chemical carriers rely on cargo, stripping and ballast pumps whose seals and impellers wear with every discharge. Bulk carriers need dependable ballast and bilge pumps for long loading operations. Container ships and car carriers run large cooling water systems where pump downtime affects the main engine. Offshore support vessels and tugs depend on fire-fighting, fuel transfer and fresh water pumps for daily work. Yachts and fishing vessels use smaller bilge, livewell and fresh water pumps that need quick replacement. We read every pump requisition with the vessel type and duty in mind, so the quotation reflects how the pump is actually used on board.
Most pump requisitions are for spares rather than whole units. We quote the parts below against your maker references and deliver them with the rest of your order.
Cartridge and component mechanical seals, gland packing and O-ring kits for centrifugal and screw pumps, matched to shaft size and maker part number.
Bronze, stainless and cast iron impellers, wear rings and casing rings to restore pump performance after wear or cavitation damage.
Ball and roller bearings, shafts, sleeves and flexible couplings for pump and motor assemblies, quoted by dimension and maker reference.
Complete overhaul kits combining seals, gaskets, bearings and fasteners, so a full pump rebuild can be done during one port call.
Replacement pumps and pump-motor sets where repair is not practical, quoted with matching flanges, voltage and capacity.
Suction and discharge hoses, foot valves, strainers and fittings that keep the pump system working. See plumbing and ventilation.
Pump parts are only useful if they fit. Our sourcing process is built around accurate identification and honest lead times.
We start from the nameplate: maker, type, serial number and, where available, the maker’s drawing and part list. A photo of the nameplate and the worn part removes most of the guesswork and shortens the quotation.
Some owners require original parts; others accept quality equivalents for consumables like seals and bearings. We mark each line clearly so the technical department can choose.
Common seals and bearings are often available quickly, while impellers and complete units can take longer. We show lead times per line and can split supply between this port and the next.
Pump spares are packed and labeled by system and delivered with your other stores at the berth, with a delivery note listing each part number for the engine room records.
If a part cannot arrive before sailing, we tell you on the quotation and can arrange supply at the vessel’s next U.S. port instead.
A failed cooling water pump or bilge pump can stop a vessel from sailing. Mark the requisition URGENT, include the nameplate details, the ETD and the port, and we will tell you quickly what can realistically be sourced and delivered before departure, and what is better planned for the next port. Requisitions can be sent through our form at any time, and urgent requests are prioritized by ETD.
Many vessels calling at U.S. ports carry pumps made in Europe, Japan, South Korea or China, and their technical departments sit in Greece, Germany, Singapore or Tokyo. We work by email across time zones and quote against the maker references your superintendent uses, so approvals are quick.
Where a European or Asian pump maker has limited stock in the United States, we tell you the realistic lead time up front and, where appropriate, suggest approved equivalent consumables so the vessel can keep running until the original part arrives.
A clear pump requisition is the difference between a same-week supply and a long back-and-forth. These steps help.
Send a clear photo of the pump and motor nameplates. Maker, type and serial number are often enough to identify the correct spare list.
Use the part numbers from the maker’s manual or the onboard spares list. If the manual is missing, describe the part and include dimensions and a photo.
Tell us whether the issue is a leaking seal, worn impeller, noisy bearing or a complete failure. It helps us suggest the right kit rather than single parts.
Give the vessel’s rotation. If a part is long lead, we can deliver it at a later U.S. port on the same voyage.
Vessel name, IMO, berth or terminal, ETA/ETD, agent details and the item list with quantities. For spares add maker, model and part number.
Every line priced, substitutes and long-lead items flagged, and delivery or launch charges confirmed up front.
Approve by email or purchase order. Suppliers and transport are booked the same day.
Stores arrive in the agreed slot at your berth at any U.S. port we serve with a delivery note matching your requisition.
Invoice and supporting documents for your accounts, audits and vessel records.
Accurate pump identification at step one is the biggest factor in quotation speed. Every pump part is checked against the requisition and part number before dispatch, and any substitution is shown on the delivery note before the engineer signs.
Send the pump maker, model, serial number and part numbers to Alpha Ship Supplies. We quote the parts and deliver them to the vessel at its berth at U.S. ports we serve, coordinated from our Houston headquarters.
Bilge, fire, ballast, sea water and fresh water cooling, fuel and lube oil transfer, sanitary, cargo and stripping pumps, plus small utility and hand pumps.
Both. We quote original parts where required and clearly mark approved equivalents for items such as seals and bearings, so your technical department can choose.
The pump and motor nameplate details, part numbers from the manual, the quantity needed, the vessel name and the port and ETA. A photo of the nameplate and the worn part helps most.
Yes. Where repair is not practical we quote a complete pump or pump-motor set matched to the duty, flange size, capacity and power supply on board.
It depends on the part. Common seals and bearings can often be supplied quickly, while impellers and complete units can take longer. Lead times are shown per line on the quotation.
Yes. Pump spares are delivered with your provisions, deck and engine stores on one delivery to the vessel.
Yes. We quote mechanical seals, wear rings and overhaul kits for cargo and stripping pumps against the maker references for tankers and chemical carriers.
We say so on the quotation and can arrange delivery at the vessel’s next U.S. port on the same voyage.
Yes. We supply bilge, livewell, fresh water and oil change pumps for yachts, fishing vessels and small craft as well as commercial ships.
Send the nameplate details, part numbers, vessel name and port. You will get a line-by-line quotation with lead times and a delivery plan to your berth.
